Push or fold is what organises your game once your stack gets short in a tournament: past a certain point the middle options disappear and two plays remain — all in or fold. It sounds crude, which is exactly why players avoid it. It's the other way round: the crudeness is what makes it profitable, because it removes every hard postflop decision precisely when you no longer have the chips to make them.
Where the push or fold zone starts
The standard marker is 10 big blinds (bb). Below that, a normal raise already commits a third of your stack: if someone re-raises, you're calling anyway — just without the advantage of having applied the pressure first.
Between 10 and 20 bb there's still room to raise and fold, especially at passive tables. Below 10 bb, shoving becomes the default. And watch the other end of the range: below 4-5 bb your all in gets called by almost anything, because the pot is laying a price to call. Your pressure disappears before your chips do.
Why it works: fold equity
An all in doesn't only win when your cards are better. It also wins — mostly wins — when nobody calls. That second route to the pot is fold equity: the value of making opponents fold.
At 9 bb you're still a threat: a mid-stack risks a real slice of their tournament to call you. At 3 bb you threaten nobody. That's why the costliest mistake isn't shoving too wide — it's shoving too late, waiting for "a better hand" while the stack melts and takes your last weapon with it.
Which hands shove (and how position changes everything)
The rule isn't a hand list. It's a hand list per position.
- UTG and early: tight. Pairs, strong aces, solid broadways. Half the table is still behind you.
- Middle positions: widen to middle aces, small pairs and high suited connectors.
- Button and small blind: the range opens dramatically. With one or two players left to act and 8 bb, any ace, any pair and most high cards are a correct shove.
The logic: the fewer players who can call, the more fold equity is worth and the less your specific hand matters. Push/fold charts to drill this sit among the software on our tools page — an hour reviewing ranges off the table beats twenty tournaments of improvising. If your short-stack range is still guesswork, start from starting hand selection and build up.
The filter most players skip: ICM
In tournaments, chips aren't worth a flat amount. Near the money, risking your whole tournament costs more than raw card math suggests — that's ICM. A shove that's profitable in chips can be a mistake in prize value when you're on the bubble with three stacks shorter than yours.
Practically: if you're the shortest and tables are about to break, tighten a few notches. If you're second shortest and someone else is on fumes, let them bust first.
The lesson
Push or fold isn't surrender — it's recognising which tool you have left and using all of it. The player who improves doesn't drift to 4 bb "waiting for a spot"; they act while pressure still means something. And they accept the uncomfortable part: you will make correct shoves that end your tournament. That's not a mistake, that's variance. The mistake is the passive fold that leaves you weaponless.
