Push/fold and ICM are where sit & gos are won and lost. Push/fold means that once your stack is short, your only preflop options are to shove all-in or fold. ICM — the Independent Chip Model — tells you what those chips are actually worth in money, and near the bubble it makes survival more valuable than accumulation. Together they explain the SNG golden rule: shove wide, call tight.
Why short stacks push or fold
When your stack drops to roughly 10–12 big blinds, a standard min-raise commits about a quarter of it, and folding to a re-raise means you’ve bled chips for nothing. Moving all-in instead does two things a raise can’t:
- It maximizes fold equity — opponents can’t float or float-then-bluff you off the pot.
- It removes tough postflop spots you’d rather not navigate with a short stack.
So you shove or fold. No min-raise-fold, no limp, no flat-call out of position. This is the backbone of SNG fundamentals.
A push/fold reference chart
Below is a simplified open-shoving guide from the button, first-in, in a single-table SNG. Treat it as a default and adjust for opponents.
| Effective stack | Button open-shove range |
|---|---|
| 12 BB | Pairs 22+, A2+, K9s+/KJo+, QTs+, JTs |
| 10 BB | Pairs, any ace, K8s+/KTo+, Q9s+, J9s+, T9s |
| 7 BB | Any pair, any ace, any king, Q8s+, J9o+ |
| 5 BB | Any pair, any ace, any king, any queen, most suited |
| 3 BB | Nearly any two cards |
Earlier seats shove tighter (more players left to act), the small blind heads-up shoves wider. Calling an opponent’s shove is a different, tighter range — never assume you can call as wide as you can shove.
ICM: why chips aren’t money
In a cash game a chip is a dollar. In an SNG it isn’t. Payouts are flat and top-heavy — first might pay 50% of the prize pool, second 30%, third 20% — so doubling your stack does not double your equity. The Independent Chip Model prices this in.
The practical consequence is that the chips you lose are worth more than the chips you win. Risking your stack on a marginal all-in can be break-even or better in chips yet clearly losing in real money. That gap is the whole reason bubble play differs from deep play. For the full mechanics, see what ICM is.
Worked example: an ICM fold that a cash player would hate
Four players remain, three get paid, payouts 50/30/20. Stacks are nearly even at ~10 BB each. The button shoves and it folds to you in the big blind with A♦ J♣ — a hand that crushes a button’s shoving range in raw chips.
In chips, calling is a clear profit: A-J beats a wide button open-shove more than half the time. In money, it’s a mistake at even stacks on the bubble. If you call and lose, you finish fourth for nothing, forfeiting a guaranteed cash. If you fold, you keep a healthy stack and a strong shot at a pay jump when someone else busts.
The ICM math tightens your calling requirement dramatically — often to something like a big pair or A-K at even stacks four-handed. So here, unless you have a specific read that the button is shoving trash, fold A-J. That fold feels wrong to a cash player and is exactly right in an SNG.
When ICM pressure is weakest
ICM isn’t equally strong everywhere:
- Winner-take-all or top-heavy spins — survival matters less, so shove and call wider.
- Early levels — no bubble in sight, so play chips more like a normal tournament.
- Once you’re the dominant chip leader — you can bully because busting costs you the least.
Knowing when to ignore ICM is as valuable as knowing when to obey it. The general tournament version of this thinking lives in our tournament strategy hub.
Common mistakes
- Calling shoves as wide as you’d shove them — calling ranges must be tighter.
- Min-raise-folding at 9 BB instead of shoving and keeping fold equity.
- Ignoring stack distribution — who covers whom changes every decision.
- Applying full ICM caution in a winner-take-all format where survival barely pays.
Put it together
Master push/fold and ICM and you master sit & gos: shove wide to steal, call tight to survive, and let the payout structure — not the chip count — guide your bubble decisions. Reinforce the basics in our SNG fundamentals guide, go deeper on the math in what ICM is, and return to the sit & go strategy hub to see how these skills apply across every format.
Frequently asked
What does push/fold mean in a sit and go?
Push/fold is a preflop strategy for short stacks where your only options are to move all-in (push) or fold — no raising and folding, no flat-calling. It applies once your stack is small enough that a raise commits you anyway, usually around 10-12 big blinds or fewer.
What is ICM in a sit and go?
ICM (Independent Chip Model) converts your chip stack into its real-money equity given the payout structure. Because SNG payouts are flat and top-heavy, chips you lose are worth more than chips you win, so ICM makes survival near the bubble more valuable than raw chip accumulation.
Why do calling ranges get tighter on the bubble?
On the bubble, busting forfeits a near-certain cash, so calling an all-in risks real money for chips you can't fully realize. ICM therefore narrows your calling range sharply, even as your open-shoving range stays wide because folds are so valuable.
What stack size should I switch to push/fold?
Around 10-12 big blinds for open-shoving, and you should already lean toward it below 15. The shorter your stack, the wider you can profitably shove from late position.
