Push/Fold Chart: Complete Strategy Guide for Tournaments
When your stack drops below 15 big blinds in a tournament, traditional poker strategy breaks down. You no longer have room to raise, get re-raised, and fold. At this point, your decision simplifies to two options: push all-in or fold. Understanding optimal push/fold strategy is one of the highest-ROI skills in tournament poker.
What Is Push/Fold Strategy?
Push/fold is a simplified game-theoretic framework for short-stack play. When your effective stack is roughly 10-15 big blinds or fewer, the mathematically optimal strategy is to either shove all your chips in pre-flop or fold your hand entirely. There is no limping, no min-raising, no seeing flops.
This approach works because with a short stack, any raise commits a large percentage of your chips. If you raise to 2.5x and get re-raised, you are pot-committed anyway. By shoving directly, you maximize your fold equity — the value you gain when opponents fold rather than calling.
How Push/Fold Charts Work
A push/fold chart maps every starting hand to a decision (push or fold) based on two factors: your position at the table and your stack size in big blinds. The charts are derived from Nash equilibrium calculations — the mathematically optimal strategy that cannot be exploited.
| Stack Size | Strategy Approach | Key Consideration |
|---|---|---|
| 1-5 BB | Push very wide | Almost any two cards from late position |
| 5-8 BB | Push wide from late, tight from early | Fold equity still matters significantly |
| 8-12 BB | Standard push/fold ranges | Position becomes increasingly important |
| 12-15 BB | Consider min-raise with premium hands | Transition zone between push/fold and normal play |
Position Matters Enormously
From the button with 8 big blinds, you can profitably shove roughly 40-50% of all hands. From under-the-gun at a full table, that range shrinks to roughly 10-15%. The reason is simple: fewer players left to act means fewer chances of running into a strong hand.
Early Position (UTG, UTG+1)
Shove only premium and strong hands: pairs (22+), strong aces (A8s+, ATo+), and broadway hands (KQs, KJs). With 6-8 players left to act, your shove will get called frequently by strong ranges.
Middle Position
You can add suited connectors (87s+), more aces (A5s+, A9o+), and king-high hands (KTs+, KJo+). The reduced number of opponents opens up your range.
Late Position (Cutoff, Button)
This is where push/fold shines. From the button, you can shove hands as weak as K4s, Q8s, J9o, and small suited aces. Only 2-3 players remain, and they need strong hands to call.
The Math Behind the Charts
Push/fold math combines two components: the probability of winning when called (your equity) and the probability that everyone folds (fold equity). Your expected value for any shove is:
EV(shove) = Fold% x (blinds + antes) + Call% x (Equity x total pot - your stack)
When the EV of shoving exceeds the EV of folding (losing your blind), the shove is profitable. Nash equilibrium charts solve this equation for every hand, position, and stack depth simultaneously.
Common Mistakes
- Waiting for a premium hand — With 5 big blinds, folding round after round bleeds chips. You must push wider than feels comfortable.
- Ignoring position — Shoving K7o from UTG is a disaster; from the button, it is often correct.
- Not adjusting for ICM — Near the money bubble, push/fold ranges tighten significantly because bust-out costs more tournament equity than chips gained.
- Open-limping short — Limping with a short stack is almost never optimal. Push or fold.
Adjusting for ICM
In bubble situations, the Nash equilibrium ranges need adjustment. When eliminating busts you out of the money, your pushing range should tighten. Conversely, when you are the big stack, you can apply pressure by pushing wider, since your opponents face ICM pressure to fold.
The Independent Chip Model quantifies this pressure through bubble factors — a multiplier that indicates how much more each chip lost costs compared to each chip gained.
