Special Teams

Overview

Special teams means any situation where the two teams do not have the same number of skaters on the ice — most often a power play (you have the extra skater) and a penalty kill (you are the team a skater short). It also covers 4-on-4, 3-on-3 overtime, and the strange states in between. Special teams decide a large share of close games, because a two-minute minor penalty hands one team an advantage that even strength never offers.

This document is about what to actually do in those situations: the shapes, the plays inside the shapes, how to get into the zone and how to stop someone getting in, and the rules that quietly govern all of it.

A note on notation. "5-on-4" means five skaters against four, goalies not counted. So a standard power play is 5-on-4, a two-man advantage is 5-on-3, coincidental penalties give 4-on-4, and regular-season overtime is 3-on-3. When a team pulls its goalie during a power play you get 6-on-4.

POWER PLAY

The one idea behind every power play

Five attackers against four defenders is not "one extra shooter". It is one extra decision the penalty kill cannot make.

Four killers can cover four attackers. That is the whole problem. A static 5-on-4 where nobody moves is, functionally, a 4-on-4 with a spare man standing somewhere useless. The advantage only becomes a goal when the kill is forced to have two attackers to worry about and one body to do it with — a 2-on-1 somewhere on the ice. A 2-on-1 anywhere is worth creating, because every one of them pulls the kill further out of shape and sets up the next one. But they are emphatically not worth the same: danger is a function of location. A 2-on-1 at the net front — net-front player plus a backdoor arriver against one defenceman — is a near-certain chance. A 2-on-1 at the top of the zone usually amounts to no more than a shot from distance into traffic. (That ranking is a coaching judgement about danger by location, not a rule — but it is the judgement every modern power play is built on.) Manufacture them wherever the kill lets you, and cash them in as close to the net as you can.

Why puck movement, not shooting, creates it

A penalty kill is a shape, and a shape has to travel to cover the puck. Every pass makes at least one killer skate. Killers skating are killers arriving late, and a killer arriving late is a 2-on-1 for the two seconds before they get there.

• A kill can cover any single option. It cannot cover three options in two seconds. That is the entire mechanism.
• Passing moves the kill faster than skating does. The puck travels far quicker than a person. Two crisp passes will pull a box further out of shape than thirty seconds of one player stickhandling on the half-wall.
• Shooting into a set kill is how you end your power play. A shot from the point into four bodies with the killers already square is a coin-flip on possession — block, clear, and now you have to re-enter the zone against a set kill, which is the single hardest thing to do in hockey. This document's default is "shoot when the kill is out of shape." That is a coaching philosophy, not a law. The realistic alternative is a genuine shot-volume power play, which is coached and does work: fire everything at the net from the moment you are set, on the theory that tips, rebounds and scrambles beat a goalie who is never allowed to settle, and that a retrieval unit which wins the loose pucks turns a "wasted" shot into a fresh setup. Volume-first suits units with a heavy point shot, a fearless net front and good retrievers; patience-first suits units with a distributor and a one-timer. Find out which one your coach wants before you decide the point shot was a bad idea.
• Corollary: the pass that beats a kill is usually the second one. The first pass makes them move; the second one arrives where they no longer are. Power plays that make one pass and shoot are just slow even-strength hockey.

What this means for you personally: whatever spot you occupy, your job is to be an option the kill must physically account for, in a body position where you could shoot or pass immediately. A player who has to take two touches to become dangerous is not an option — the kill can ignore them and cover the other three.

Power play formations

1-3-1 — the modern default

The shape: one player at the point (the blue line), three across the middle of the zone — two on the half-walls (the boards roughly level with the faceoff dot, between the corner and the point) with a bumper between them in the middle of the slot — and one at the net front.

That is one point player, not two. Most NHL first units run the 1-3-1 with four forwards and a single defenceman, and that defenceman is the point.

The jobs:

• Point (the "quarterback"). Usually the lone defenceman. You are a distributor first and a shooter second. Walk the line laterally — moving three metres sideways changes the angle of every passing lane in the zone and forces the killers' heads to turn. Your shot exists mainly as a threat: the moment the kill stops respecting it, they stop stepping out to you, and the half-walls lose their space. Shoot for tips and rebounds, not to beat the goalie clean through four bodies.
• Half-walls (two players, usually forwards). The primary decision-makers. From here you can reach the point, the bumper, the net front and — through the seam — the far half-wall. Ideally you play your off-wing (a left-hander on the right side, or vice versa) so the puck is on your inside hand: that opens your body to the middle of the ice, makes the one-timer available, and lets you shoot or pass without turning. Your first move should almost always be to look inside before you look up.
• Bumper. The middle of the three, sitting in the soft spot between the point and the net-front player, roughly the middle of the slot. You are the reason a box fails: a box has nobody assigned to the middle. Your job is to keep your stick free and your blade on the ice for a one-touch shot or redirect, to constantly adjust your angle so a passing lane exists from at least one half-wall, and to hold the kill's high players down so they cannot step out and pressure the point.
• Net front. Screen the goalie, tip point shots, hunt rebounds, and occasionally slide below the goal line to open a high-to-low pass. Live at the edge of the blue paint — the painted goal crease in front of the net, the goalie's protected ice — not inside it. See the goaltender-interference note under Center.

Who plays the bumper? Most often the centre, because the position is a centre's whole skill set: soft hands in traffic, back to the play, one-touch passing. But this is genuinely team-dependent, not a law — plenty of real NHL units put a winger in the bumper. The spot is chosen for the ability to receive and release in a crowd, not for what is printed on the lineup card. Ask your coach who has it; do not assume.

Strengths: occupies all five dangerous areas at once; creates four passing triangles, so there is always a short outlet; the bumper attacks the one place a box cannot cover; the off-wing half-walls make the cross-seam one-timer live at all times.

Weaknesses: every player must be comfortable making plays under pressure — a weak link in any of the five spots kills it. With only one player back, a lost puck at the blue line is an immediate odd-man rush the other way. It is also the most-scouted shape in hockey, so kills arrive with a plan (usually a diamond) specifically for it.

Suits: skilled units with at least one high-end distributor on a half-wall, one genuine one-timer threat, and a centre or winger brave enough to stand in the slot.

Umbrella — three high

The shape: three players high, arranged as an arc rather than a flat line — that curve is what the name describes. One apex sits highest, in the middle at or just inside the blue line, and the two flanks sit lower than the apex on either side. Below the arc sit two low players, typically one at the net front and one at the side of the net or in a circle.

How far the flanks drop is the one real variation. In the classic version the apex is a forward in the middle of the blue line with both defencemen out on the flanks, still close to the line — the arc is shallow. In the modern version the lone defenceman takes the apex and two forwards drop right down to the tops of the faceoff circles, where the one-timer lives — a much deeper arc. Both are umbrellas. What neither is, is three players strung out level across the blue line: with no depth between them every pass is short and lateral and the kill barely has to move.

There is no bumper in a true umbrella. The middle of the slot is deliberately vacated so the high players have clean shooting lanes into it.

The jobs: the three high move the puck side to side looking to get it to the middle for a shot with a lane; the two low screen, tip and collect rebounds. Everything is aimed at getting a puck through to the net with a body in front of the goalie.

Strengths: enormous space and time up high; hard to pressure, because pressuring one high player opens a pass to another; three shooting angles from the top; very difficult for the kill to get a shorthanded break, because you always have players above the puck.

Weaknesses: it is far from the net, and goalies and killers are most comfortable when the puck is far from the net. Used as a permanent shape it becomes predictable, and a diamond or an aggressive box will happily let you pass it around the top all night. It concedes the middle of the ice by design.

Suits: teams with heavy, accurate point shots and a genuinely fearless net front; also a good change-up shape when a kill has settled comfortably against your 1-3-1.

Overload — four to one side

The shape: four players loaded onto one side of the ice — typically a player below the goal line, one in the corner or low circle, one on the half-wall and one at the point on that side — with the fifth player weak side as a release valve and safety.

The jobs: cycle the puck relentlessly in a small area, creating repeated 3-on-2s along the strong-side wall until a killer over-commits, then either attack the resulting seam or swing the puck cross-ice to the lone weak-side player for a shot with the goalie moving.

Strengths: outnumbers the kill locally; generates chances from deception and short passes rather than long ones; excellent against a passive box that will not come out to the wall.

Weaknesses: demands deceptive, patient passers — if the kill reads the pattern, the passes are short and easy to intercept, and interceptions on the strong side lead straight to shorthanded breaks. It also produces fewer shots than other shapes; a unit that cycles without ever pulling the trigger achieves nothing but a tired power play.

Suits: skilled, patient units, and teams whose best player is a below-the-goal-line playmaker. Note that at rec and youth level overload is often run out of a 2-3 base (below), with both defencemen staying at the points.

Spread / box — pulling the kill apart

The shape: five spots, deliberately stretched to the corners of the danger area — two low, one on each side of the net just outside the posts; two high and wide, at the tops of the circles or the points; and one in the middle of the slot. The point is not the shape itself but the spacing: stand far enough apart that one killer cannot cover two of you.

The jobs: occupy space, stay still enough to be a genuine passing target, and force the kill to make full-length skates to close anyone down. Everything is a one-touch play — with this much space the kill's only defence is anticipation, and one-touch passing beats anticipation.

Strengths: the maximum geometric stress you can put on a small defensive unit. Creates backdoor plays almost automatically, because the weak-side low player is simply too far away for the kill's low defender to reach.

Weaknesses: at 5-on-4 the passes are long, and long passes are interceptable and can be blocked by a well-placed stick. It surrenders the possession game — you are not cycling, you are waiting.

Suits: it is the standard 5-on-3 shape (see below), and it is worth using at 5-on-4 against a kill that has collapsed so tightly it has conceded the outside entirely.

2-3 — the older structure

The shape: two defencemen at the points and three forwards low — one at the net front, one in each circle or corner. This was the default power play for decades and remains extremely common in rec, beer-league and youth hockey.

The jobs: the points shoot and keep pucks in; the three forwards work the low area, screen, tip and hunt rebounds; the puck generally goes low-to-high and back.

Strengths: it is safe. Two defencemen at the line means very few shorthanded breaks and very good puck retrieval on missed shots. It is also the easiest shape to teach and the least dependent on individual skill — everyone knows where to stand.

Weaknesses: it attacks the two areas a box is built to defend (the points and the goalmouth) and ignores the middle of the slot entirely. It generates lots of low-quality shots. Against a competent box it is close to harmless.

Suits: teams without a puck-moving defenceman, teams who are protecting a lead, and any group that has not yet learned to hold the blue line under pressure. It is a perfectly respectable place to start.

The key power-play plays

These are the plays the shapes exist to produce. Learn the plays first; the shape is just where you stand to make them available.

The seam pass

A seam is a passing lane that runs through or across the middle of the defensive shape rather than around it — most often half-wall to half-wall, or half-wall to bumper.

• It works because a kill's shape is built to defend the perimeter. Any puck that crosses the middle forces every killer and the goalie to re-orient at once.
• How to throw one — flat, hard, on the ice, to the receiver's stick, with a look or a fake sold first — is standard passing technique under pressure, covered in Passing and Receiving. What is special-teams-specific is the judgement: if the seam is not there, do not force it. A seam pass intercepted in the middle is a shorthanded breakaway, and you have four teammates above the puck.

The one-timer from the off-wing

A one-timer is a shot taken directly off an incoming pass without stopping the puck. Playing your off-wing (left-hander on the right side, right-hander on the left) puts the puck on your inside hand and turns your whole body toward the net, which is what makes it possible. The shooting mechanics — weight loaded on the back foot, body still and square before the pass leaves — are in Shooting.

The power-play point is a different one: the threat is worth as much as the shot. A live one-timer option on the weak side forces one killer to stay wide, and that is precisely how the bumper and the net front get free. You are being useful in the two seconds before the puck ever comes to you.

The royal road / slot-line pass

The royal road (also called the slot line) is an imaginary line running straight down the middle of the ice from net to net. A pass that crosses it immediately before a shot is the most dangerous single event in offensive hockey. (Published descriptions of exactly where the line runs disagree — some put it net-centre to net-centre as here, others stop it at the top of the circles. Shooting sets out the disagreement; nothing here turns on which is right.)

• Why it works: a goalie who has to track the puck across the middle cannot stay square. They must break from small shuffles into a hard lateral push, and while pushing they are opening up, off their angle and off their depth. The shot arrives before they are set. See Goaltender for the save mechanics from the other side.
• The concept was popularised by former NHL goaltender Steve Valiquette, whose shot-tracking work classified chances by whether the puck crossed the line. The best-sourced measured figure is 15.50% — the finishing rate on shots following a royal road / cross-slot pass, the highest-value pass type measured, roughly double the next one (Alan Wells' analysis of Ryan Stimson's Passing Project data, via NHL.com). Carry its qualification with it, because that qualification is part of the fact: the Passing Project was volunteer-tracked, the sample is "51,308 shots at 5v5", and the percentage counts all attempts, not shots on goal — and note where that qualification comes from: it is not in the NHL.com article, which gives only the 15.50% figure. The sample size and the all-attempts basis are stated by Wells himself, in Weighted Shot Rates Based on the Passing Project (Hockey Graphs, 6 September 2016) — so it is not comparable with a shots-on-goal conversion rate, and it is not a power-play measurement. Offensive Zone Play owns this figure and its limits. Use that number, with those words attached. ⚠️ The 20–30% range you will see quoted in coaching material has no published primary source behind it — it is not a power-play-specific measurement of the same thing, because nobody has published a separate power-play conversion rate for seam passes; treat it as illustrative only. Valiquette's own "76% of goals are green shots" split does at least trace back to Valiquette himself — he gave the figure directly to NHL.com in December 2014, along with the detail that 30% of goals came on plays with a pass or carry across the royal road — but the Clear Sight Analytics tracking underneath it is proprietary and has never been replicated. Shooting sets out that source and its limits in full; Offensive Zone Play carries the same figures. The direction of the effect is not in doubt, and it is why every modern power play is designed around cross-ice passing.
• Practical version: a cross-seam pass beats a shot from the same spot almost every time. Before you shoot from a half-wall, check the far side.

The point shot for tips and rebounds

The point shot is not an attempt to score from the point. It is a delivery system for a tip or a rebound, and should be judged on whether it arrives low, hard and on net with a body in front. Release, weight transfer and getting a shot through a blocking lane are in Shooting.

The two special-teams reads: shoot when the net-front player has established position and the goalie's view is obstructed, not before — screening a goalie from outside the crease, without touching them and without crowding them so they cannot move, is legal — and change the angle first, because walking two or three metres along the line takes the shot out of the lane the kill has set. A missed net on a power play is a free clear off the end boards and twenty seconds gone.

The backdoor play

The backdoor is the weak-side post — the far side of the net, away from the puck. Whenever the kill's low defender commits to the strong side or to the net-front player, it is a 2-on-1 with nobody defending it.

Arrive late. A player standing at the back post all shift is marked; a player arriving as the shot or pass is released is not. Time it, do not camp it. The pass comes low-to-high-to-backdoor or straight across from below the goal line — either way it crosses the royal road, which is why it converts.

The walk-down from the half-wall

The walk-down is the half-wall player skating the puck down toward the goal line and inside rather than passing. It forces a decision: if the kill's low defender steps out to you, the net front is free; if they stay, you have a shot from the top of the circle with a moving goalie.

Walk to the middle, not to the corner — below the goal line and wide you are harmless, and the threat comes from heading toward the dot. Head up, feet moving toward the net; the moment your feet stop the kill resets. If it is denied, reset to the point and start over. Losing the puck below the goal line on a power play is a wasted twenty seconds and usually a clear.

Power play zone entries

This is where most amateur power plays die — not in the zone. A kill defending its blue line is compact, has four players between you and the net, and has nothing to lose by conceding the neutral zone, while you have to bring a five-player structure through a narrow gate without a turnover. Units drill the in-zone setup for hours and the entry for minutes, then wonder why they never get set up.

The entry toolkit itself — carry, chip, dump, delay, the drive-and-drop, and the data on what each is worth — is in Zone Entries, and everything there applies here. What changes with the extra man is only this:

1. A clean, controlled entry is worth far more than a fast one. Enter with possession and set up, and you have ninety seconds of pressure. Dump and lose the race and you have ten, then you do it all again. (The tracked data in Zone Entries still favours the carry-in on the power play — roughly two and a half times the shots of a dump-in — but by a narrower margin than at even strength, because the extra man also makes dump-in retrievals easier. Read the figures there rather than restating them; the advantage is real, it just is not larger than usual.)
2. You do not get many attempts. A failed entry — dump, lose the race, regroup, come again — burns a serious slice of a 120-second advantage. Two or three of those and the penalty is over. (There is no measured figure for the cost of a failed entry; treat this as calibration, not data.)
3. The drop pass is the signature power-play entry, because it changes the carrier without changing the speed of the attack and makes the defending line commit to the wrong player. Arik Parnass's tracking for the Special Teams Project across six NHL teams in 2015-16 found drop-pass entries produced 0.84 shot attempts per entry versus 0.70 for other entries — but took 15.5 seconds to execute versus 12.6, which cancels most of the gain. (His three categories run drop 15.49 s, regular 12.56 s, stretch pass 10.37 s. 12.6 is the figure that pairs with the 0.70, because he removed stretch-pass results from the non-drop bucket; comparing the drop against the stretch's 10.4 s instead is not like for like.) His conclusion is the sensible one, and it is about your own team rather than theirs: keep both a polished regular scheme and a drop scheme, and go to the drop when your primary scheme is in a slump. (Decade-old, small-sample study — indicative, not settled.) Every kill now expects it, and a drop stolen at the red line is a shorthanded breakaway.
4. The swing — one or two players arcing back to gather speed and receive already moving forward — solves the entry's hardest problem: arriving at the line with speed and the puck at once. The single swing (one forward swings, one stays wide) is less predictable than the double.
5. Dump to a spot, not a player. The extra man means you will usually win a loose-puck race in the corner if you time the arrival. Rim away from the goalie's trapezoid — the marked area behind the net where an NHL, KHL or IIHF goalie may legally play the puck; most rec and youth leagues do not have one — so a defender has to retrieve under pressure. See Defender.
6. Regroup rather than force. Curl back out, reset to the point defenceman or the goalie, re-form the swing, attack with new speed and a different pattern. You can afford this and the kill cannot — they are tiring while you are not. The cost is clock, so do not regroup out of habit. A puck turned over at the offensive blue line with four teammates ahead of it is the way coaches most often name for a power play conceding a shorthanded goal — coaching consensus rather than a counted breakdown; nobody publishes shorthanded goals classified by the play that produced them, the same limit that applies to the prevalence claims elsewhere here.

Retrievals and keeping possession

Most of a power play is not the set play. It is the twenty seconds of scrambling after the kill clears it or blocks a shot. Units that win here get three or four setups per power play; units that lose here get one.

When the kill clears it

• Decide in advance who chases. Most teams send the net-front player or the weak-side half-wall and leave the point at the line. If two players chase, nobody is holding the zone.
• The chaser's job is not to win the puck — it is to arrive before the puck stops. A rolling puck retrieved on the move can be moved immediately; a dead puck against the boards is a battle you might lose.
• Everyone else re-forms while the chase is happening, not after. If the retrieval succeeds and the shape is not rebuilt, you have possession and no options.
• If the clear leaves the zone entirely, do not chase it in ones and twos. Regroup as a unit and re-enter properly — see the entries section above. A disorganised re-entry loses more time than a calm one.

The defenceman's job holding the line

If you are the lone point player in a 1-3-1, keeping the puck in the zone is your first responsibility and shooting is your second. A power play that gets cleared has to re-enter, and re-entry is the hardest thing in hockey.

• Stay inside the blue line. Drifting out into the neutral zone is not offside — offside is only ever judged at the instant the puck crosses the line into the zone (Rule 83.1), and a puck already in the zone cannot make you offside. The real cost is simpler: with your skates outside the line you are no longer an option for a pass, and if the puck reaches you there the zone is cleared and the whole unit has to re-enter against a set kill.
• Take the puck off the wall with your feet already moving laterally, not standing square to the boards — that is how clears go past you.
• Body on the wall, stick low and flat. Most clears on the power play are along the boards at ankle height.
• A hold you miss is a 2-on-0. With one defenceman back, "keep it in at all costs" is wrong. If the clear beats you cleanly, turn and skate; do not lunge. See Risk Management.
• Holding the line is not pinching, and the difference matters here. Holding means staying at the offensive blue line and stopping the puck leaving. (Do not call it "stepping up" — a step up is moving forward to challenge an attacker early, in the neutral zone or at your own blue line. Different end of the rink, different play. See Rink Map and Glossary.) Pinching means leaving the line and stepping down the wall into the zone to attack a puck below you. Holding is the point player's standing job on a power play. Pinching is an extra risk you take on top of it, and with one defenceman back it is almost never worth taking — a missed pinch puts you two strides deeper than a missed hold does.
• If your team runs two defencemen (umbrella, 2-3), only one holds aggressively at a time — the other backs up as the safety. Same partnership discipline as an even-strength pinch, described in Defender.

5-on-3

A two-man advantage is a different game, not a better power play. It should almost always produce a goal, and when it does not it is nearly always because the unit played it like a 5-on-4.

Why it is different: three killers can defend a triangle. They will sit in a tight triangle around the slot — usually two low in front of the net and one high — concede everything outside it, and block shots. Sustained pressure on the puck is not available to them, because every killer who leaves the triangle opens a hole nobody can fill. That does not mean you will never be touched: a three-man kill will still jump a bobbled reception, close hard on anyone who walks into the slot, and throw a stick or a body at a shooter. What it means is that nobody is coming to hunt you on the perimeter — so you have time out there that does not exist at 5-on-4, and the only way to lose it is to hurry.

How to play it:

• Spread out into the spread/box shape above, and make the triangle try to cover the whole zone.
• Move the puck side to side across the royal road, not around the perimeter. Every cross-ice pass forces the goalie into a full lateral push; three or four in a row and they will not be set. Do not shoot from the outside into three shot-blockers — with nobody hunting you there is no reason to rush, so wait for the goalie to be moving.
• The goal usually comes from a one-timer at the far post or the second-wave rebound. Have someone at the net for both. Be patient but not passive: two minutes of pretty passing with no shot is a failed 5-on-3.

Rules that matter here:

• A team never plays with fewer than three skaters. If a third player is penalised while two are already serving, the third penalty's clock does not start until one of the first two expires (a delayed penalty in the Rule 26 sense), and the team may put a substitute on the ice to stay at three (NHL Rule 26.1). So a 5-on-2 does not exist.
• A goal only releases one penalty. When you score against a shorthanded team, the minor penalty with the least time remaining terminates (Rule 16.2). A 5-on-3 therefore becomes a 5-on-4, not a 5-on-5 — and if you were about to get another chance, take it immediately while the kill is reorganising.
• This does not apply to major penalties, which are served in full regardless of goals, and does not apply to penalty-shot goals (Rule 16.2).

PENALTY KILL

The one idea behind every penalty kill

You cannot cover five players with four. So stop trying. A penalty kill is a decision about which shot you are willing to give up — and then a two-minute exercise in making sure that is the only shot you give up.

Every kill concedes something. A box concedes the middle of the slot. A diamond concedes the outside and the backdoor. A wedge+1 concedes the perimeter. The failure mode is always the same: a killer decides to cover something that was never theirs, and the thing that was theirs becomes a goal. Discipline beats effort on a penalty kill, every time.

The second idea: time is on your side and nothing else is. Two minutes is not long. A kill that concedes zero clean looks for 40 seconds and then breaks is worse than one that concedes three shots from the point and never breaks.

---

Penalty kill formations

Box — the shape everyone learns first

The shape: a rectangle around the slot. Two players high — both forwards, one on each side, each responsible for one point — and two players low, both defencemen, covering the two low corners and the goalmouth.

A box has no single "top". Two forwards, side by side, is the whole point. If you find yourself describing "the top of the box", you are describing a diamond.

The jobs:

• High forwards: deny the point players time and space, stay in shooting lanes, and never both drift to the same side. Your inside shoulder should be turned so you can see your point man and the middle at once.
• Low defencemen: the strong-side D pressures the puck when it comes below the goal line or to the low circle; the weak-side D owns the goalmouth and the backdoor. Same partnership logic as even-strength Defensive Zone Coverage.
• Everyone: the box slides with the puck rather than rotating. When the puck moves across, all four shift together, keeping the shape intact.

Strengths: simple, teachable, hard to break down, and excellent at protecting the goalmouth and the low slot. Very good against an overload, which it can simply out-wait, and against a 2-3, whose entire attack aims at the two areas a box defends best.

Weaknesses: nobody in a box is assigned to the middle of the slot. Against a 1-3-1 the bumper stands in the hole in the middle of your rectangle and is uncovered by design. It is also passive by nature: a box that never pressures gives a skilled unit unlimited time on the perimeter to find the seam.

Diamond — a single apex

The shape: one player high at the apex, two in the middle on either side, and one low. A diamond, not a rectangle: it has exactly one player at the top.

Why it exists: because a box leaves the bumper unmarked. The diamond's two middle players squeeze the middle of the slot from either side, so the 1-3-1's bumper can be accounted for. Coaches also use it against a three-high umbrella, where the apex can pressure the middle point man who would otherwise have a free shot.

The jobs:

• Apex (often the centre, but this varies by team): pressure the point player, take away the middle shooting lane, and do not get walked around. You are the only player up there — if you overcommit, the point is uncovered.
• Two middles: each takes a half-wall, and both collapse onto the bumper when the puck goes to the middle. You are working two jobs at once; the timing of when you leave the wall for the middle is the whole art of playing this position.
• Low: own the goalmouth. You are alone down there.

Strengths: the only common shape that starts with an answer to the bumper; puts real pressure on the point; encourages turnovers high in the zone, which is where shorthanded chances come from.

Weaknesses: narrow. A quick cross-seam pass to the far half-wall pulls it apart, and the far-side one-timer is available if the middles are slow. The single low player is alone against a net-front presence and a backdoor arriver — a genuine 2-on-1 that you are choosing to concede. Also more mentally demanding than a box; a confused diamond is worse than a competent box.

Wedge+1 (also called triangle-and-one)

The shape: three killers hold a tight triangle around the net — two defencemen just off the crease edges, one forward at the mid-to-high slot — while the fourth player, the "+1", chases the puck around the perimeter.

The jobs:

• The wedge (three players): stay tight, protect the slot and the goalmouth, block shots, and rotate as a connected unit. You do not chase. Your shape barely moves.
• The +1: apply straight-line pressure to whoever has the puck, working outward from the net. Your job is to make every possession uncomfortable, not to win the puck.
• The exchange: when your pressure forces the puck to move, the nearest wedge player becomes the new +1 and you drop into the triangle. This handover is the hard part and the reason the system needs practice — everyone must know who is out and who is in, every second.

Strengths: it protects the highest-danger ice absolutely while still applying pressure, which is why it is commonly used at NHL level — The Coaches Site describes it as popular with most NHL clubs, though no league-wide count of who runs what is published, so treat the prevalence claim as unverified. It is very hard for a 1-3-1 to get a clean look at the middle. It creates turnovers and therefore shorthanded chances.

Weaknesses: high cognitive load — it demands constant awareness of a rotating assignment, which is why it is a poor choice for a young or ad-hoc unit. If the +1 chases without purpose, you are effectively killing with three players.

Aggressive versus passive

Every shape has a pressure setting, and it is a separate decision from the shape itself.

• Passive: hold the structure, concede the perimeter, block lanes, wait for a clear. Lowest variance. Right when you are protecting a lead, when you are tired, when the opposition power play is much better than you, or late in a kill.
• Aggressive: attack the puck carrier and try to force errors. The best-known version is the Czech press, where the high forward genuinely attacks the point player rather than just threatening to. Higher variance: it forces mistakes and creates shorthanded chances, but it also creates chaos, and chaos with four players against five is not usually your friend.
• The honest trade-off: the coaching consensus is that aggression pushes shots outside and to the wings while passivity concedes fewer shots overall but allows more of them from close range. That trade-off is a coaching claim, not a measured one — no published tracking data separates shot location by penalty-kill pressure setting, so treat it as unverified. What is not in doubt is the structural point: pressure spends a killer to buy a mistake, and if the mistake does not come you are defending five with three.
• The one rule: pressure as a unit or not at all. One player pressuring while the other three sit is how seams open.

The PK forecheck and neutral-zone pressure schemes

A forecheck is pressure applied in the opponent's end; a neutral-zone scheme is how you meet them between the blue lines. On the kill these are the same conversation, because the whole point is deciding where to make the power play uncomfortable.

F1/F2 are roles, not people — defined by who is first and second to the puck, not by position.

The four you will meet

• The 1-3 — one forward up on the puck, the other forward and both defencemen in a line across the ice behind him. In the passive version F1 gives token pressure to make the power play commit to a side while the three behind back up in unison, refusing to be split; the goal is not to win the puck, it is to make them dump it in. In the same-side press version F1 angles the carrier to one side and F2 closes from that side to force a dump or a turnover — more pressure, but it needs killers who can read and accelerate. Weakness: beat F1 or spread the three-line and there is a lot of ice behind it.
• The 1-1-2 — F1 up on the puck, F2 layered behind on the same side forming a wall parallel to the boards, two defencemen abreast near the line. Aggressive without over-committing; it bleeds clock and forces contested entries. Coaching material commonly describes it as a current NHL default for neutral-zone pressure, which is a different decision from the in-zone shape above, not a competing one — and that prevalence claim is not independently verified. Weakness: quick direction changes and drop passes at the red line slide underneath F1 and F2 at once.
• The retreating box (2-2) — two forwards abreast, two defencemen abreast, all four backing up together. Purely reactive, safe, easy, and vulnerable to drop passes and direction changes.
• Tandem pressure — two forwards take turns attacking the carrier, one peeling off as the other arrives. Exhausting to play against and exhausting to play; if both get beaten at once the kill is a 2-on-2 with no support.

Killing the entry — what all of this is for

The most effective place to kill a penalty is before the puck enters your zone, and every scheme above serves that one sentence. The reason is arithmetic: a power play that never gets set up never gets to use its extra man. Once they are established in a shape you are managing damage; in the neutral zone you are 4-on-5 in a space where you can dictate.

• Take away the middle and force them to one side. A power play made to enter along one boards has removed half its own options. Angle with your body, not your stick.
• Stand up at the blue line as a pair. Both defencemen step, or both retreat. One of each is a hole.
• Attack the receiver, not just the carrier. The dangerous player on entry is usually the one arriving with speed off a drop or a swing. Taking away the target is easier than taking away the puck.
• Make them dump it. A dump-in with your defencemen already turned is a win. You do not have to force turnovers to kill a penalty; you just have to keep them out. Force three failed entries and the penalty is over without you ever defending your own zone.
• Do not lunge or dive at the blue line. A missed poke check at your own line is a clean entry with you out of the play and your team down two.

Pressure or retreat? Judge it in this order: (1) Can you actually get there — pressure arriving a stride late is worse than none, because you have spent a player for nothing. (2) Where is the puck — attack a carrier looking down, receiving badly, or facing the boards; never one with head up and support both sides. (3) What is the clock — pressure early while you are fresh; in the last 30 seconds or when gassed, retreat and make them beat structure. (4) What is the score — protecting a one-goal lead late is not the time for the Czech press; see Game Management. (5) Who is on — a unit with one elite carrier is often worth attacking; five good passers will punish you for it.

Clearing, blocking, sticks and discipline

You may ice the puck freely — where your rule set allows it

Under NHL Rule 81.1, icing applies only to a team "equal or superior in numerical strength (power-play)" to the opponent, and Rule 81.6 states it directly: "If the puck was so shot by a player of a side below the numerical strength of the opposing team, play shall continue and the icing violation shall not be called." A shorthanded team cannot be iced. The test is whether you are below the opponent's strength, not who is serving the penalty — so at 4-on-4 both teams can be iced (equal strength), and at 6-on-4 with the power play's goalie pulled the four-skater team still cannot be.

⚠️ Do not stretch "numerical strength" beyond penalties. It is a natural-sounding leap to say that five skaters defending a pulled goalie are below six and so cannot be iced. They can be, and the rulebook says so three ways: Rule 81.1 glosses the term as "equal or superior in numerical strength (power-play)"; Rule 84.1 counts a goalkeeper inside numerical strength, setting overtime at "three (3) skaters and one (1) goalkeeper", so six against six is equal; and Rule 81.3 expressly preserves an icing call where the opposing "goalkeeper is legitimately out of the crease in an attempt to go to the players' bench to be substituted for an extra attacker" — "the icing should not be nullified." Defending a 6-on-5 is handled in Game Management.

There are two carve-outs — never state the exemption without them.

Carve-out 1 — the NHL's empty penalty bench, written into Rule 81.6 itself. A team shorthanded by reason of a major penalty that has "neglected to ensure there is a player on the penalty bench to exit upon the expiry of the penalty" is not permitted to ice the puck — the rule says flatly, "Icing will be called." They keep playing shorthanded and may substitute for the penalised player at the next stoppage. In practice this is an administrative failure on the bench, not a playing decision, but it means the exemption is not quite unconditional: on a five-minute major, make sure somebody is sitting in the box ready to come out.

Carve-out 2 — USA Hockey restricts the exemption by classification, and for most readers this is the one that matters. The nullification in USA Hockey Rule 624(b)(1) is prefixed with a classification limit: "(For all Youth 15-Only and above, Girls 16U and above, High School and Adult classifications only) The offending team is short-handed (below the on-ice numerical strength of their opponent) when the puck is shot." Below those levels the nullification simply does not exist, so a shorthanded team cannot ice the puck at all — a length-of-the-ice clear on the kill comes straight back for a defensive-zone draw. If you play or coach youth hockey under USA Hockey rules, the single biggest structural advantage described in this section is not available to you, and a kill built on clearing the length of the ice will just feed the power play repeated defensive-zone faceoffs.

When is it judged? The rulebook does not state a general "moment of the shot" test, so what follows is an interpretation drawn from the two places it does put a timestamp on. Rule 81.4 says that for the line-change ban "the determination of players on ice will be made when the puck leaves the offending player's stick." Rule 81.6 says that when a penalty is about to expire, icing is judged "at the instant the penalty expires" — and, explicitly, "should the puck be released from the stick of the player shooting the puck down the ice prior to the penalty expiring, the icing infraction shall not apply." Both point the same way: release the puck before your penalty expires and you are still exempt, even if the penalty ends while the puck is travelling. That is a real tactical detail — with two seconds left on the kill, fire it.

How to use it:

• Fire it the length of the ice the moment you have it. There is no penalty, no faceoff, and no line-change restriction. This is your single biggest structural advantage on a kill.
• You do not need to look for a teammate. Getting the puck 200 feet away buys you a few seconds of clock and, crucially, a chance to change tired players. (How many seconds depends entirely on how fast they retrieve and regroup; there is no measured figure to put on it.)
• Aim to make the retrieval awkward — into the corner away from their goalie's trapezoid, or hard around the boards — so they cannot set up a clean regroup.
• Beware the one thing that is still a penalty: under Rule 63.2(iii), shooting or batting the puck directly (non-deflected) out of the playing surface from your defending zone is a minor for delay of game — even while shorthanded. There is no penalty-kill exception. Off the glass and staying in is fine; a deflection out is fine; a clean flip over the glass is a second penalty and a 5-on-3 against you. Aim your clears hard and flat, not high. Three written exceptions matter on a kill:
  • "Except where there is no glass" — the rule's own wording. Where the boards have no glass above them (the bench areas in some rinks, and many rec facilities), the penalty does not apply.
  • Into the players' benches. The rule's NOTE: "When the puck is shot into the players' bench, the penalty will not apply." But shooting it over the glass behind the benches is penalised.
  • Directly off a faceoff. The same NOTE: "When the puck goes out of the playing area directly off a face-off, no penalty shall be assessed." This is the one you will actually use — on a defensive-zone draw while shorthanded, a centre who wins the puck straight out of the rink has given up a faceoff, not a penalty.
• Also under Rule 63.2(v), a skater other than the goalie who deliberately falls on or gathers the puck into his body takes a minor. Smothering the puck to beg for a whistle is not a legal kill tactic.

Shot blocking

Blocking shots is a technique, not an act of courage. The technique — how close to get, how to present the biggest surface, why to stay on your feet — is in Body Contact and Battles and Defender, and this document does not repeat it.

Two things are specific to the kill:

• You are blocking on purpose, not by accident, which means you should be in the lane before the shot, not sliding into it. Sliding gets you a puck off the ankle and a shooter who has already changed his angle.
• Never block from a screening position. Half-deflecting a shot your goalie could not see is worse than letting it through cleanly. If you cannot get properly into the lane, get out of it.

Stick lanes

The most valuable and least visible thing you do on a kill.

• Blade flat on the ice, out in front of your body, in the passing lane — not on the puck carrier. Sticks in lanes deter far more passes than they intercept.
• Take away the seam first, and point the stick at the most dangerous option rather than at the puck. The puck is being handled by someone your teammate already has; the perimeter pass is the one you are happy to concede.
• Stay in a low stance with your knees bent. You cannot make a quick lateral adjustment from standing.

The discipline not to chase

The power play wants you to chase. Every pass around the perimeter is an invitation, and perimeter possession is not a threat — taking the bait is. If you chase and miss, you have created the seam yourself: four players cannot cover a five-man shape with one of them out of position.

Chase only when the puck can actually be won — a bobbled reception, a player with their back turned, a puck on the boards with no support. Talk constantly while you do it; most kill breakdowns are two players making different assumptions rather than two players being lazy, so call switches, call the bumper, call the backdoor (On-Ice Communication). And change when you can, not when you must — a tired killer chases. Clear, then change, in that order.

---

Shorthanded offence

A shorthanded rush is one of the highest-value plays in hockey and one of the easiest ways to lose a game. The difference is entirely the read.

Take it when you have a genuine odd-man rush — a 2-on-1 or a breakaway — that the turnover handed you rather than one you have to manufacture with speed; when the turnover happened above the puck, so their players are behind you (a power play with four players below the puck is defenceless); and when you can get there before their point player recovers. If it is a footrace you will lose, it is not a rush.

Do not take it when it is a 2-on-2 or worse — lose the puck and you are 4-on-5 again with two players out of the play and them entering with speed; when your partner has not seen it, so the "rush" is you alone turning it over at their line and skating 180 feet back; when you are protecting a lead late (clear it and change — see Game Management); or when you are the last player back. That last one is obvious and it still happens every week.

The default is always: get the puck out, then change. The rush is the exception you take when it is free. If you have to think about whether it is on, it is not on. Fuller treatment of the trade-off in Risk Management.

BOTH

4-on-4 and 3-on-3

4-on-4

Coincidental penalties (below) put both teams at four skaters. Two fewer bodies on the same sheet changes the game more than the numbers suggest: each player has a quarter more ice, and the extra room is mostly in the middle, so skill and skating matter more and structure matters less.

• You have one fewer support layer defensively. With only two forwards back, the backchecking centre's middle-lane job (see Center) becomes everyone's problem, and a 2-on-1 arrives faster and with more room.
• Defencemen should activate less, not more. The open ice tempts you into the rush; the punishment for being caught is an immediate odd-man rush the other way.
• Change with extreme care — a change with the puck live at 4-on-4 hands them a rush against three. Change on possession in the offensive zone, or after a clear.
• Support the puck, do not spread out. The instinct in open ice is to stretch; the right play is short support options and quick movement, exactly as at 5-on-5.

3-on-3 overtime

NHL regular-season overtime is five minutes of 3-on-3, sudden death, followed by a shootout if nobody scores (Rule 84.1, 84.4). Playoff overtime is full 20-minute periods at 5-on-5 — the 3-on-3 format does not apply (Rule 84.5).

How the game changes: there is no forecheck worth the name, no cycle, and nowhere to hide. Everything is possession and odd-man rushes.

Strategy that actually works:

• Possession is the whole game. You cannot be scored on while you have the puck. The format has shifted from run-and-gun to a deliberate, possession-first approach precisely because of this.
• The regroup is a weapon. Carrying the puck back out of the offensive zone into the neutral zone to reset — rather than forcing a low-percentage attack — is standard practice at NHL level. (It is unpopular with fans, and the League's general managers have discussed limiting it. Reporting the November 2023 GM meetings for NHL.com, Dan Rosen wrote that Colin Campbell, the NHL's senior executive vice president of hockey operations, said there is a growing concern about the regroup in 3-on-3 overtime, when teams cross the blue line with possession but pull it back out into the neutral zone to reset and retain possession — and that Campbell said the talking points included potentially eliminating the ability to pull the puck out of the attacking zone once you cross the blue line. Those are Rosen's words summarising Campbell, not Campbell's own; the article carries no direct quotation from him on the regroup. But discussion is not adoption: the NHL Official Rules 2025-2026 contain no restriction on regrouping, in overtime or otherwise, so as of writing the regroup remains entirely legal. Flagged as a live issue, not a rule.)
• Attack only with a numerical advantage. A 2-on-1 in 3-on-3 is nearly a goal. A 1-on-1 is nothing. Wait for the extra man rather than driving into a set defender.
• Never change on the fly with the puck loose. A bad change at 3-on-3 is a breakaway. Teams change by holding possession — often passing back to the goalie, who retains and replays it: settles it, keeps it live, and moves it back out once the change is made. Not freezes it. A goalie who covers the puck in his crease to cause a stoppage is a minor under Rule 63.2(vii) unless he is actually being checked, and a stoppage hands the draw and the reset to the other team anyway.
• Isolate and attack. With one defender to beat, the point is to get a defender alone in space and go at them. Support arrives too slowly to help them.
• Do not chase the puck as a group. Three players chasing is nobody home.

Penalties in overtime (Rule 84.3), which are worth knowing because they decide games:

• A penalty in 3-on-3 overtime makes it 4-on-3, not 3-on-2 — the non-offending team adds a skater. The three-skater floor from the 5-on-3 section above is what forces this.
• If both teams take a minor at the same stoppage with nothing else on the clock, play continues 3-on-3.
• A two-man advantage in overtime is played 5-on-3: the offending team stays at three and the other team goes to five.
• Carry-over: 5-on-3 at the end of regulation starts overtime 5-on-3; 4-on-4 at the end of regulation starts overtime 3-on-3.
• Pulled goalies in regular-season overtime cannot change on the fly. Rule 84.2: once removed for an extra attacker, the goalie "must wait for the next stoppage of play before returning to his position. He cannot change 'on the fly.' If he does, a bench minor penalty shall be assessed for having an ineligible player."

Coincidental penalties, expiring penalties and 6-on-4

Coincidental penalties

Under NHL Rule 19.1, when one minor is assessed to a player from each team at the same stoppage, with nothing else on the penalty clocks, the penalties are served without substitution and both teams play 4-on-4 for two minutes.

• If at least one team was already shorthanded, the rule works differently: immediate substitution is made for the matching penalties, so the on-ice strength does not change, and those players wait for the first stoppage after their time expires to come out.
• Coincidental minors do not make either team "shorthanded" (Rule 16.2). This matters: a goal scored during 4-on-4 does not release anybody from the box.
• Where multiple penalties are assessed at once, referees cancel out equal numbers of majors first and then equal numbers of minors, and any remaining time differential is served normally (Rule 19.5).
• Rec and minor-hockey leagues frequently differ here — several play coincidental minors with immediate substitution so both teams stay at five. Check your league.

Penalties expiring

The seconds around a penalty ending are among the most dangerous in hockey, in both directions.

• A goal against a shorthanded team ends the minor with the least time remaining (Rule 16.2). Minors and bench minors only — not majors, and not when the goal comes on a penalty shot.
• On the power play, know the clock. The last ten seconds are your best chance: the kill is watching the clock too, and their concentration dips.
• On the kill, the player coming out of the box is a fresh attacker arriving from the side of the rink at full speed with nobody assigned to him. Whoever is nearest must call it — "man coming out!" is one of the most useful things anyone says on a rink — and pick him up. If you are the player leaving the box, sprint; you are the most dangerous player on the ice for about three seconds. While you are in there, watch the play, not the clock, and come out facing the ice.

6-on-4

Pulling the goalie during a power play, late in a game, to make it 6-on-4.

• It is the largest advantage in hockey and is used far less than the arithmetic suggests: two extra attackers against four killers means genuine 2-on-1s everywhere and a kill that cannot pressure at all. The kill's counter is the empty net, and it is a real one — a killer who wins a puck can clear it 180 feet into that net legally, because icing does not apply to a shorthanded team and a puck that enters the net is a goal regardless.
• As the power play: put two at the net front and send the extra body where it forces a decision — the bumper or the backdoor, never the perimeter. Move the puck quickly and accept that blocking lanes will be crowded.
• As the kill: shot blocking and stick lanes matter more than ever, clear with your head up looking for the empty net, and remember that over the glass from your own zone is still a penalty.
• A related situation: on a delayed penalty in the Rule 15.1 sense — the referee's arm is up, the infraction has been signalled, and the offending team does not yet have the puck — the non-offending team pulls its goalie for a 6-on-5. Play continues until the team to be penalised gains control of the puck (Rule 15.1), so the risk is not a shot against; it is your own player shooting the puck into your own empty net. See Breakouts for how to play the puck in that window.

Faceoffs on special teams

Faceoffs matter disproportionately when the numbers are uneven: with a man advantage, winning the draw means you skip the zone entry entirely — the hardest part of the power play, gone. A skater short, losing the draw means defending a set power play from the first second. Technique, alignment and the set plays themselves are in Faceoffs; what follows is only the special-teams-specific rules layer, and it is the part almost nobody knows.

The four rules that give you an edge here — verify these against your own league:

• The team awarded the power play chooses which end-zone dot the draw takes place at to start the power play (Rule 76.2). Pick the side that suits your one-timer, not the side the puck happened to be on.

• Following an icing, the attacking team chooses the dot (Rule 81.2) — and on special teams this cuts the opposite way to the way most players assume. The kill cannot be called for icing (Rule 81.6 — subject to the two carve-outs above, the NHL's empty penalty bench on a major and USA Hockey's classification limit), so where the exemption applies this essentially never comes up against them. (Read that the right way round: the kill may shoot the puck the length of the ice as much as it likes; what it cannot do is be whistled for it.) It comes up when the power play ices it, which is entirely possible and happens on a rushed clear after a failed entry. The draw then goes back to the power-play team's own end; the attacking team at that end is the penalty kill, so the kill picks the dot, the power play cannot change lines (Rule 81.4) and cannot take a timeout — that second one is Rule 87.1: "No time-out shall be granted to the defensive team following an icing." — and you have handed a tired unit a defensive-zone draw while a man up. On a power play, never fire a loose puck the length of the ice. IIHF Rules 81.2, 81.4 and 87.1 impose all three consequences in the same words, so this is the position for British and European league hockey as well; USA Hockey imposes neither the line-change ban nor the timeout ban, so the self-inflicted wound is smaller there.

• Encroachment gets your centre ejected from the dot, not the encroaching player (Rule 76.6). A winger whose skate crosses into the circle, or who creeps into the area between the hash marks before the drop, costs you your best draw-taker on the most important faceoff of the shift. A second violation by the same team on the same draw is a bench minor (Rule 76.7) — on the kill, that is a 5-on-3 against you. Related: do not crowd the scrum after a penalty is called; players coming into the attacking zone beyond the outer edge of the end-zone circle during a gathering move the draw out to the neutral zone (Rule 76.2), throwing away your offensive-zone start for nothing.

• The home team has last change — but not after its own icing. Rule 82.1 gives the visiting team first change, then: "The home team may then make any desired substitution, except in cases following an icing, which does not result in the delay of the game." Later in the same rule the exception is identified: "A team that is in violation of Rule 63.8 – Delaying the Game or Rule 81 – Icing shall not be permitted to make any player substitutions prior to the ensuing face-off."

  Those are the same bar stated twice, and the second statement is the one that says whose. Rule 81.4 repeats it in the same words, with the same three exceptions (a goalkeeper who had come off for an extra attacker, an injured player, a penalty affecting on-ice strength) — none of which would make sense if both benches were frozen. The team that iced it cannot change; the other team can.

  What that means on special teams: if your unit ices the puck you cannot change, home or away — that is the expensive one. But if the opponent ices it, you get the free matchup wherever you are playing, and at home you still get it last. See Faceoffs, which covers the same situation from the draw's point of view.

What to actually do: agree the play before you line up — on the power play, whether you are winning it back to the point, to the half-wall, or forward; on the kill, whether you are winning it clean for a clear or tying up for a winger to sweep, and where that clear is going.

---

The goalie's role on both

Your goaltender is a full participant in both special teams, not a bystander. The goalie's own game — depth, tracking, save selection under a screen — is in Goaltender. Four things you have to do about it:

• On the kill, tell them what you are conceding. If the plan is to concede point shots, they will set their depth for a shot through traffic instead of holding for a seam pass. A kill that never says this makes its goalie guess.
• On the kill, agree the retrieval before it starts. Under NHL, KHL and IIHF rules your goalie may only play the puck behind the goal line inside the trapezoid, but they can stop a rim behind the net and leave it stationary for you. Where there is no trapezoid — most rec and youth leagues — they are a genuine third puck-handler and your clears get far easier. See Breakouts.
• On the power play, use them as a reset. On a 5-on-4 regroup, passing back to the goalie is a legitimate way to buy a couple of seconds and change the angle of attack. They are also your safety on a failed entry, which is another reason not to force one.
• Against their goalie, know the line. Screening from outside the crease, in the sightline, without contact, is legal and is the single most valuable thing a net-front player does. But the qualifier attaches to the impairment, not to where your skates are: Rule 69.1 disallows the goal where an attacker "either by his positioning or by contact, impairs the goalkeeper's ability to move freely within his crease or defend his goal" — positioning alone can do it. Standing outside the paint is not a safe harbour if you have crowded them out of their own crease. Contact inside the crease that impairs a save is out; incidental contact outside it is fine if you made a reasonable effort to avoid it (Rule 69.4), and a rebound scramble is expressly carved out (Rule 69.7).

Common Mistakes

These are errors the body above does not cover — the ones that survive knowing the systems.

• Icing the puck while on the power play. Nothing in the numerical-strength exemption protects the team with the extra man. You hand the kill the choice of dot, you cannot change (Rule 81.4), you cannot take a timeout (Rule 87.1), and a tired unit now defends a draw in its own end. The IIHF book imposes all three identically, so this holds in British and European league hockey; USA Hockey imposes only the defensive-zone draw. On the power play, a rushed length-of-ice clear is a self-inflicted wound.
• Assuming last change is automatic at home. It is not, after your own icing. If you are the home team and you ice it, the visitors change and you do not (Rules 81.4 and 82.1) — Rule 82.1's exception reads "except in cases following an icing, which does not result in the delay of the game", and the rule's later paragraph identifies who it catches: the team in violation of Rule 81. After a visitor's icing your last change is intact. Plan the matchup accordingly, and remember that your own icing forfeits it. See Faceoffs.
• Winning a shorthanded defensive-zone draw straight out of the rink and bracing for a penalty. Rule 63.2(iii)'s note exempts a puck that leaves the playing area directly off a faceoff. It is a faceoff, not a minor. Knowing this stops a centre steering a draw he should be firing.
• Sending your best draw-taker out and then having a winger creep over the hash marks. The encroaching player is not the one ejected — your centre is. On the kill, a second violation on the same draw is a bench minor and a 5-on-3 against — or, under USA Hockey Rule 613(d), a minor on the individual who committed it, which is the same 5-on-3. Faceoffs owns the full split.
• Confusing the two things called a "delayed penalty." Players pull a goalie because they heard "delayed penalty" when what was actually announced was a third penalty stacking on the clock. Listen for the referee's raised arm, not the phrase.
• Reading "the kill can't be pressured at 5-on-3" as "nobody will touch me." Three killers will still jump a bobble and close on anyone walking into the slot. What you have is time on the perimeter, not immunity.
• Treating a 2-on-1 at the top of the zone as the objective. Creating it is a step, not the finish. Cash it in near the net, where the shot is actually worth something.
• Blocking a shot from a screening position and deflecting a puck your goalie never saw. The most common shot-blocking error on a kill, and it is worse than not blocking at all.
• Describing a 1-3-1 as having "defencemen at the points". It has one point player. Two means you are running an umbrella, an overload or a 2-3 — call it what it is, so the person next to you knows where to stand.
• Standing three players level across the blue line and calling it an umbrella. With no depth between them, every pass is short and lateral and the kill barely moves. An umbrella is an arc: apex highest in the middle, flanks lower — barely lower in the classic version with both defencemen out wide, all the way down to the tops of the circles in the modern one.
• Too many men on the ice during a special-teams change. Units change together; count before you go. It is the only penalty in hockey that is purely an administrative failure.
• Arguing about the system on the bench instead of before the game. Almost every special-teams breakdown is two players operating on different assumptions, and the fix is a thirty-second conversation in the room.

1. A man advantage is a 2-on-1 waiting to be created. Five against four is nothing until the kill has two things to cover and one body to do it with. Create them anywhere; cash them in near the net, because danger is a function of location.
2. Puck movement, not shooting, creates it. A kill can cover any single option; it cannot cover three options in two seconds.
3. The 1-3-1 has exactly one player at the point — one point, two half-walls, one bumper, one net front — and most first units run four forwards and a single defenceman. The bumper is most often the centre, but that is a team choice, not a rule.
4. Most power plays die at the blue line, not in the zone. Drill entries — drop, swing, carry, controlled dump and the regroup — and be willing to reset rather than force one.
5. A pass that crosses the middle of the ice before a shot is the most dangerous play in hockey, because a goalie moving laterally cannot be set. Before you shoot from a half-wall, check the far side.
6. A penalty kill is a decision about which shot you are willing to concede, then two minutes of discipline making sure it is the only one. A box concedes the middle; a diamond concedes the outside and the backdoor; a wedge+1 concedes the perimeter.
7. A box has two players high and no single top; a diamond has one apex. Use the diamond against a 1-3-1, because a box leaves the bumper unmarked.
8. The best place to kill a penalty is before the puck enters your zone. Three failed entries and the penalty is over.
9. You may ice the puck freely while shorthanded — but check your book first, and never ice it while on the power play. Where it applies, the exemption (Rule 81.6) is the kill's biggest structural advantage. It has two carve-outs: the NHL withdraws it from a team shorthanded by a major that has left nobody on the penalty bench, and USA Hockey grants it only at Youth 15-Only and above, Girls 16U and above, High School and Adult (Rule 624(b)(1)) — below those levels a shorthanded team cannot ice the puck at all, so a kill built on length-of-the-ice clears just feeds the power play defensive-zone draws. Over the glass from your own zone is a second penalty either way. And a power play that ices it hands the kill the choice of dot and forbids itself a line change.
10. Know your team's shape, and your job inside it, before the puck drops. These are coaching choices, and almost every breakdown is two players assuming different systems.

Royal road: Kevin Woodley — "Unmasked: Analytics provide new evaluation tools", NHL.com, 18 December 2014 — Valiquette quoted directly on the 76% green-shot share and the 30% royal-road share; the original NHL.com URL now 404s, so the Internet Archive capture is linked · Taking a look at Steve Valiquette's "Royal Road" — Blue Seat Blogs (Justin Rutherford, 9 January 2015) · The Royal Road: Where to draw the line — Vital Hockey Skills — note that these two sources are reporting different quantities, not disagreeing about one. Blue Seat Blogs gives Valiquette's 76%/24% share of goals by shot type and contains no conversion rate and no 30% figure at all; the 30% is Valiquette's royal-road share of goals, from the Woodley NHL.com piece above. Vital Hockey Skills is the one giving conversion rates, and its 33%/3% pair is itself second-hand — it attributes them there to Chris Boyle of Sportsnet's Shot Quality Project. Shares of goals and conversion rates are not comparable, which is why the exact number stays flagged as unverified in the text.
