Short Stack Poker Strategy: GTO Push/Fold Ranges (2026)
When your stack drops to 15 big blinds or less, conventional poker strategy stops working. No more 3-bets, c-bets, or turn barrels — it’s binary. Here’s exactly what GTO says to do.
What is push/fold strategy?
Push/fold is the GTO approach to short-stack play. When your stack reaches roughly 15 big blinds, the math changes fundamentally: a standard open-raise commits so much of your stack that folding to a 3-bet becomes -EV, and calling a reshove is nearly forced. So GTO eliminates the middle step — you either shove all-in preflop or fold.
This isn’t a simplified “beginner” strategy. Push/fold is what Nash equilibrium solvers produce for stacks under 15BB. At this depth, the optimal play genuinely is binary: any other approach (open-limping, min-raising, open-folding with hands that should shove) loses EV compared to pure push/fold.
The critical threshold is around 15 big blinds. Above that, normal open-raise/fold strategy applies. Below it, push/fold takes over. At exactly 15BB the lines start to blur — many solvers mix between open-raising and shoving with certain hands, but as a practical rule, simplify to pure push/fold at 15BB and under.
Why short-stack spots decide tournaments
The bubble, the final table, the money ladder — the biggest money decisions in tournament poker happen when stacks are short. Most players understand this intellectually but still wing these spots.
A recreational player at 12BB UTG asking “should I shove A7o?” is really asking a math question with a precise GTO answer. The answer changes based on your position, the number of players left to act, ante structure, and ICM pressure. Getting it wrong — either folding too much and blinding out, or shoving too wide and busting unnecessarily — is one of the highest-EV leaks in tournament poker.
The players who make deep runs consistently don’t guess in these spots. They know their push/fold ranges cold, because they’ve drilled them until the decisions are automatic.
GTO push ranges by position (15BB)
At exactly 15BB with no antes (a standard 9-handed tournament), GTO push ranges look roughly like this. These are approximate Nash equilibrium ranges — the exact hands shift slightly based on solver parameters and stack depths, but these are reliable baselines:
UTG (Under the Gun)
~17% of hands77+, A9s+, AJo+, KQs
Tightest range. Seven players left to act means you need real equity.
MP (Middle Position)
~22% of hands66+, A7s+, A9o+, KTs+, KQo, QJs
Slightly wider. Fewer players behind, more fold equity.
CO (Cutoff)
~31% of hands55+, A4s+, A7o+, K9s+, KJo+, QTs+, QJo, JTs
Meaningful widening. Three players left means good steal equity.
BTN (Button)
~42% of hands44+, A2s+, A4o+, K6s+, K9o+, Q9s+, QTo+, J9s+, JTo, T9s
Only two players left (blinds). Widest range. Steal equity is high.
SB (Small Blind)
~55% of hands33+, A2+, K5s+, K8o+, Q8s+, QTo+, J8s+, JTo, T8s+, 98s
Very wide. Only the BB left. Fold equity is excellent.
Note: These are approximate 9-handed ranges without antes. With antes in play, all positions widen by roughly 15–25% due to dead money in the pot.
How antes change your push ranges
Antes are the single biggest modifier of push/fold ranges. When antes are in play — which is most tournament stages past level 3 or 4 — there’s already significant dead money in the pot before anyone acts. That dead money makes shoving more profitable because you’re winning a larger pot when everyone folds.
As a rule of thumb: with antes, expand every position’s push range by approximately 20–25%. Hands that were borderline folds without antes — like A5o from UTG at 15BB — become clear shoves once antes are in play.
Big Blind Antes (BBA) — where a single player posts an ante equal to the big blind — have become standard in major tournaments and most online MTTs. With a BBA structure, the ante is even larger relative to the blinds, widening push ranges further compared to traditional button-ante or no-ante formats.
ICM and short-stack push/fold
Pure Nash equilibrium push/fold charts assume chip EV — chips won = chips lost in value. That’s accurate in a cash game, but tournament poker uses ICM (Independent Chip Model) where your stack has diminishing marginal value as you accumulate chips.
In ICM-weighted spots — near a pay jump, on the bubble, at a final table — push ranges tighten and call ranges tighten even more. The general rule:
Bubble / pay jumps: Tighten your push range by roughly 5–10% compared to Nash. A7o UTG might be a nash shove, but ICM makes it a fold on a tight bubble.
Big stacks to your left: Being covered (short-stacked when a large stack is in the blinds) tightens your range because a call is more likely and more damaging.
Calling ranges tighten dramatically under ICM. A caller needs better equity to justify calling an all-in when the ICM cost of busting is high — especially in big-stack vs. short-stack spots.
This is why short-stack players often find more fold equity at final tables than the pure Nash charts suggest — the big stacks don’t want to risk their tournament life calling a 12BB shove with A9o when the payout difference between spots is significant.

Push/fold by stack depth: 5BB to 20BB
Push/fold ranges change at every big blind increment. Here’s how your BTN shove range scales from a desperate 5BB to a playable 20BB — the range where a standard raise is viable again:
| Stack (BTN) | Approx. Push % | Key threshold |
|---|---|---|
| 5BB | ~65% | Nearly any two that connect. Fold equity is minimal — shove wide. |
| 8BB | ~55% | Still very wide. Any ace, most broadways, any pair. |
| 10BB | ~50% | Standard short-stack. A2+, 22+, most broadways from BTN. |
| 12BB | ~45% | A3o now folds. Weak kings become borderline. Fold equity improving. |
| 15BB | ~42% | Full push/fold territory. Can standard open-raise with some hands too. |
| 20BB | ~35% | Mix of open-raise and shove. Normal raise-fold viable with strongest hands. |
The 4 most costly short-stack mistakes
1. Open-limping at 12BB
At 12BB, a standard raise commits 25% of your stack and you can't comfortably fold to a 3-bet. Either shove or fold. Limping gives away cheap information and doesn't build fold equity.
2. Folding shoves because "it feels risky"
At 10BB in the SB with A8o, shoving is correct even though it feels like a big spot. The math works: fold equity + equity when called = positive EV. Playing scared leads to blinding down to zero fold equity.
3. Calling off with dominated hands
Being short-stacked as a caller is not the same as being short-stacked as the shover. K9o calling a 14BB UTG shove is a disaster — you're dominated by AK, KQ, KJ, KT. Calling ranges stay tight even when your stack is short.
4. Ignoring position entirely
Shoving 87s from UTG at 10BB is –EV. The same shove from the BTN is +EV. Position is the single biggest variable in push/fold math. Most short-stack errors come from applying late-position ranges in early position.
Real hand examples: what GTO says
Example 1 — CO, 12BB, no antes
Hand: A6o. Action folds to you.
GTO answer: Shove. With three players left to act (BTN, SB, BB), fold equity is meaningful. A6o has enough equity to be +EV as a shove from CO at 12BB. The mistake is min-raising — you’re putting in 2BB and have to fold to any 3-bet, wasting equity.
Example 2 — UTG, 10BB, big blind ante
Hand: KTo. 9-handed table.
GTO answer: Shove. With antes creating more dead money, KTo from UTG becomes a +EV shove at 10BB. Without antes, it’s borderline. This is the single most important ante adjustment — antes make UTG shoves with hands like KTo and QJo profitable when they otherwise wouldn’t be.
Example 3 — SB, 8BB, three players left (bubble)
Hand: 74o. Action folds to you.
GTO answer: Fold (ICM adjusted). In a pure Nash spot, 74o from SB at 8BB is actually a shove — the range is that wide. But on a tight bubble with ICM pressure, fold. The cost of busting when you’re about to cash is too high for a hand with minimal equity and no redraws when called.
How to actually memorize push/fold ranges
Reading push/fold charts doesn’t make the decisions feel automatic at the table. You need reps — hundreds of them — where you see a hand, a position, and a stack size and make the call without thinking.
The most effective practice method: flashcard-style drilling. Present yourself with a scenario (BTN, 11BB, KJo, no antes — shove?) and answer instantly before checking. It’s the same muscle memory that makes good players make these decisions in under 5 seconds at the table.
Preflop Wizard is built exactly for this. The app presents preflop scenarios — including short-stack push/fold spots — and gives you instant GTO feedback plus AI coaching that explains the why. After a few weeks of daily drilling, the ranges stop feeling like memorization and start feeling like intuition.

Frequently asked questions
At what stack size should I switch to push/fold?
The standard threshold is 15 big blinds. Below 15BB, pure push/fold is usually correct — open-raising and folding to a 3-bet wastes too much stack. At 15BB, you can mix between shoving and open-raising with your strongest hands. Above 15BB, standard raise-fold strategy applies.
Should I ever call instead of shove with a short stack?
Calling all-in is almost never correct when you have less than 15BB as the first player to act — you gain no fold equity. The exception is if someone else shoves and you have a calling range. Calling behind a shover is different from open-limping; the former is sometimes correct (especially with premium hands), the latter rarely is.
Does push/fold strategy change in cash games vs. tournaments?
Yes, significantly. In cash games, chips are worth their face value, so pure Nash equilibrium charts apply without ICM adjustment. In tournaments, ICM means stacks near the bubble or at final tables should tighten push ranges (and especially calling ranges) versus what Nash equilibrium suggests. Cash game short-stack push/fold is generally wider.
What hands should I never fold at 10BB?
With 10BB or less, folding any pocket pair or any ace preflop when you're first in is almost always a mistake — these hands have too much equity. AXs, any pair, and most broadways should be shoves from any position at 10BB. Folding them means blinding down to even worse spots.
How do I practice push/fold ranges without software?
The best low-tech method: write down a scenario (position, stack, hand), answer it, then check against a push/fold chart. Do 20–30 reps per session. For faster feedback with GTO coaching, Preflop Wizard drills these spots in a flashcard format directly on your phone.
