How to Play a Medium Stack in Tournaments
A medium stack is the trickiest to play — too deep to shove, too short to call off. Here's how to handle 20–40 big blinds, with a worked re-steal example.

A medium stack — roughly 20 to 40 big blinds — is the hardest size to play well: too deep to just shove like a short stack, too shallow to run the full deep-stacked game. The winning approach is to use your stack as a re-steal threat, apply pressure rather than call it, and avoid bloating pots out of position where a single big bet can commit you.
Why the medium stack is awkward
Short stacks have it easy in one sense: under about 10 big blinds it’s shove or fold, a nearly solved decision. Deep stacks have room to play speculative pots, float, and make big folds — the full toolkit covered in deep-stack play.
The medium stack sits between them with the worst of both:
- Too deep to shove. Moving all-in for 30 big blinds risks far more than you need to and gets called by a tighter, stronger range.
- Too short to play deep. A single pot-sized bet on two streets can put your whole stack in, so you can’t chase speculative draws freely.
Every hand becomes a judgment call. That’s why it’s nicknamed the awkward stack.
The re-steal: your best weapon
The medium stack’s superpower is the re-steal — 3-betting an opener with the plan of winning the pot before the flop. With 25–35 big blinds you have exactly the right leverage: your 3-bet is big enough to make the original raiser fold, but small enough that you’re not risking your whole stack.
Against a habitual late-position stealer, a 3-bet to around 8–9 big blinds threatens their steal for a price they’ll usually decline. You don’t need a hand — you need a spot where the opener is weak and folds often. This is aggression that wins pots without a showdown, which is exactly what a medium stack wants.
Stack-size sub-zones
Not all medium stacks play the same. Split the range:
| Stack (BB) | Character | Priority |
|---|---|---|
| 30–40 | Comfortable medium | Play position, 3-bet, some postflop |
| 20–30 | True awkward zone | Re-steal spots, avoid marginal calls |
| 15–20 | Approaching short | Push-fold creeping in, pick shove spots |
As you drift toward 15 big blinds, the re-steal shrinks into a re-shove and you edge back into short-stack territory. Above 35–40, you regain room to play more postflop and pick up speculative hands in position.
Worked example: a 28-BB re-steal
Blinds 1,000/2,000 with antes, and a loose player opens to 4,500 from the cutoff. You’re on the button with A♥ J♣ and a 28-big-blind stack (56,000).
- Fold? Too tight — A-J is well ahead of a wide cutoff steal.
- Flat call? Playable, but it invites the blinds in and leaves you guessing postflop out of a bloated pot.
- 3-bet to ~13,000? Correct. You threaten the loose opener’s steal, fold out most of their range, and often win it right there. If they shove, A-J against a wide range isn’t a disaster call — but the plan is to win preflop, not to get it in.
The re-steal turns a medium stack from passive to dangerous, using position and leverage instead of a big hand. It’s a textbook case of why acting last matters.
ICM and the medium stack
Near a pay jump, the medium stack feels ICM pressure the most. You have enough chips that busting forfeits real money, but not enough to bully with impunity. That means:
- Attack the smaller medium stacks who are also trying to survive.
- Avoid tangling with big stacks who can bust you — you’re a prime target for their pressure.
- Don’t call off marginally. Re-steal to win pots; folding a thin spot preserves your leverage and your equity.

Common medium-stack mistakes
- Calling raises out of position. Bloating pots with a stack that can’t play deep is the classic leak.
- Passively blinding down. Fold too much and you slide into a short stack with no fold equity left.
- Calling all-ins with marginal hands. Your edge is applying pressure, not paying it off.
- Ignoring the sub-zones. A 35-BB stack and an 18-BB stack are both “medium” but play very differently.
The bottom line
The medium stack rewards controlled aggression: threaten with re-steals, play position, and refuse to get stuck in expensive marginal pots. Handle the awkward zone well and you protect your chips while pressuring everyone else — the exact recipe for climbing into the big-stack seat. See where it fits in the tournament strategy hub.
Frequently asked
How do you play a medium stack in a poker tournament?
A medium stack of roughly 20–40 big blinds plays a mix of postflop poker and preflop leverage. You still open and 3-bet, but you avoid bloating pots out of position and pick clear spots to commit. The key skill is using your stack as a re-steal threat against aggressive openers rather than getting stuck in expensive marginal pots.
What is a medium stack in tournament poker?
A medium stack is roughly 20 to 40 big blinds — too deep to move all-in preflop like a short stack, but too shallow to play the full deep-stacked game without risking commitment. It's often called the awkward stack because it forces careful decisions on almost every hand.
Why is a medium stack hard to play?
Because you're stuck between two clear strategies. You can't rely on push-fold like a short stack, and you can't play speculative deep-stacked pots freely because a big bet can pot-commit you. Every marginal spot risks either wasting fold equity or committing chips you'd rather keep, so decisions are tighter and more situational.
Should a medium stack call all-ins?
Rarely with marginal hands. A medium stack's power is in applying pressure, not calling it off. Because busting forfeits ICM value near a pay jump, you should re-steal and 3-bet to win pots uncontested far more often than you flat an all-in with a hand that's only a small favorite.
