The honest answer to “when do I just shove” is that it arrives before most players think. Somewhere around 15 big blinds, the middle options start losing money quietly. Raise to two and a half big blinds out of twelve, watch somebody move in behind you, and you are choosing between folding a fifth of your stack and calling off with a hand you never wanted to call with. One book draws the line at 12: at that depth and below, it says, you are in push all-in or fold mode. That is a simplification rather than a law, and it is a good one to learn first.
The reason is not that you are about to blind out. That framing gets people shoving too early, and books warn about it directly. The reason is arithmetic: the shorter your stack, the fewer chips you risk to win the same blinds and antes, so more hands clear the bar for a profitable shove. The push/fold charts publish shove ranges by seat for the short-stack depths, with their assumptions stated: the pot is unopened when it reaches you, the table is nine-handed, and the numbers count chips rather than prize money. What follows is the part a chart cannot tell you, which is why the shove is the move and where it goes wrong.
Why shoving beats raising when you are short
Fold equity is the engine
An all-in wins the pot immediately every time everyone folds, and at 12 big blinds the blinds and antes you collect are a real fraction of your stack. Those uncontested pots are not a consolation prize, they are most of what the strategy earns. The books’ framing is worth keeping: you are risking fewer chips to win the same reward, so the shorter you get, the more hands clear that bar.
Raise-folding bleeds the stack you need
Raising small with a short stack invites the worst outcome available: you put chips in and then let go of them. Books build small-blind strategies around exactly that problem, moving hands that do not want to raise and then fold against a jam into a different part of the strategy, and keeping the raising range for hands that can call a jam. Deliberate raise-folding does exist at these depths in the hands of players who have planned the whole sequence. Raising because a shove felt too big is not that plan, and it is the version that empties short stacks.
You do not want a postflop pot at this depth
Open-shove 8 big blinds and the hand becomes one decision followed by a showdown. Put a third of it in and see a flop instead, and you are playing the same money across three streets with more ways to get it wrong, out of position most of the time. A jam removes the streets you are least equipped to play at that depth.
Where push/fold starts
There is no single line, and books name several depths for good reasons. Everything below assumes the simplest case, the one the charts assume too: the pot is unopened when the action reaches you, the table is full, and you are counting chips rather than prize money.
| Stack | What the simplification looks like |
|---|---|
| Above 20 big blinds | Normal raising, tighter when the players behind can jam over you |
| 15 to 20 | Shoves enter the picture, and the small blind starts mixing pushes with limps |
| 12 to 15 | Mixed: some shoves, some limps, plenty of folds, and raises still exist from late seats |
| Under 12 | One book’s cutoff for push all-in or fold, which is where the charts do their work |
| Under 6 | Ranges get very wide, and position moves them more than at any other depth |
Read that table as a ladder of defaults rather than a set of switches. Real short-stack play still contains small raises from the button and limps from the small blind at depths where the chart says shove, which the chart page says in its own words, and satellites break the top row entirely by making survival worth more than chips.
The other pressure is time. Every orbit costs you a big blind and a small blind, plus antes, so waiting for a premium hand is not free: the stack you are protecting shrinks while you protect it. The preflop charts cover what raising looks like at the depths above this table, which is where you want to be playing whenever you can.
What changes what you shove
Position. Later is wider, and it is not a small effect. From the button two hands are left to get through. From an early seat at a full table there are several, and every one of them can wake up.
Antes. More dead money in the middle means the pot you win uncontested is bigger, so the bar for a profitable shove drops. Ante levels are where short-stack ranges open up.
Who is behind you. A big blind who calls everything removes the fold equity your shove was built on. Read the stacks too, and read them carefully: a player who would be all in by calling is sometimes the tightest seat at the table and sometimes the loosest, depending on what the price and the payouts are doing to them.
The bubble. Near the money, chips stop being worth the same to everybody, because busting costs real prize money. That does not simply mean everyone tightens: a big stack can pressure the players who cannot afford to call, while the stack that would bust by calling folds hands it would otherwise play. The correction has a name, ICM, and the chart page has a version built for it. It is the one adjustment worth deferring to a chart rather than eyeballing.
Use the chart, learn the shape
Charts are for memorising, and the memory that survives is a shape rather than a grid. Three things worth carrying from the push/fold charts without reproducing them:
- Pairs are the backbone. They are in every seat’s range, and the smallest ones come in as you move to later seats. Even at 10 big blinds the tightest early-position ranges start a little above deuces.
- Aces come in early, and suited beats offsuit at the margin. Ace-rag suited is a shove from seats where its offsuit twin is a fold, which is not the same as saying the kicker stops mattering.
- Broadway hands widen with position. King-jack from the button and king-jack from an early seat are different hands.
Books do not rank those classes in a strict order, and neither should you. What they do show is how far the ranges stretch once the stack gets very short: at 5 big blinds the small blind is shoving the large majority of hands while the earliest seat is still folding most of them. Same depth, opposite lists, which is the clearest sign that seat and stack are doing more work here than the cards are.
The mistakes that leak chips
Limping into a pot you cannot defend
Off the small blind, limping short gives everyone behind a cheap look at a flop you cannot play. The exception is the small-blind mixed strategy above, and it is an exception with a plan attached, not a habit.
Min-raising when you are already committed
A raise that leaves you three big blinds behind has already committed you, and it asks your opponent to risk less to find out. If the chips are going in either way, put them in while the size of the bet still pressures somebody.
Calling off with a hand that only looks strong
Shoving ranges and calling ranges are not the same list. Ace-eight can be a shove from late position and a poor call against an early-position shove, because the range coming at you from up front beats it. Read the two lists separately.
Waiting for a premium until you have four big blinds
The most expensive mistake on the list. At four big blinds nobody is folding to your shove, so the fold equity you were saving up has already gone. Shoving a mediocre hand at 12 usually beats shoving a good one at 4.
Common questions
What stack size is push or fold?
There is no single line, and books name several. Around 20 big blinds you are still raising normally, just more carefully. Around 15 you are in mixed territory, where some hands shove, some limp from the small blind and the rest fold. At 12 and below, one book calls it plainly: you are in push all-in or fold mode. Under about 6 big blinds the ranges get very wide and the seat you are in moves them a long way. Treat 15 as the depth where the idea starts mattering and 12 as the depth where it takes over, for an unopened pot at a full table with chips rather than prize money on the line. Change those conditions and the depth moves.
Should you ever limp with 10 big blinds?
From the small blind, yes, and books describe exactly that: a mixed strategy in the 10 to 15 big blind range where some hands push, some limp and the rest fold. It is the hardest short-stack line to run properly, because you need a plan for what happens when the big blind raises. Everywhere else at that depth, shoving or folding is the strategy that costs you least.
Do push/fold ranges change on the bubble?
Yes, and not always in the same direction. Busting costs real prize money near the money, so the stack that would be eliminated by calling plays tighter, while a stack that covers the table can shove wider precisely because the players behind cannot afford to call. That adjustment has a name, ICM, and the push/fold charts include an ICM version that prices busting at what it actually costs at that stage. Use it near the money instead of guessing at the correction.
