20bb Resteal
20bb Resteal
A tournament poker strategy where a player with approximately 20 big blinds re-raises (3-bets) an opponent's open raise to exploit fold equity and accumulate chips, often from late position against a likely wide opening range.
Overview
20bb Resteal is a crucial concept in tournament poker, especially during the middle and late stages when stack sizes are shallow. It refers to a three-bet (re-raise) made by a player with about 20 big blinds (bb) against an initial raiser. The goal is to capitalize on the perceived weakness of the opener's range and the high fold equity that comes with a short but not desperate stack.
Why 20 Big Blinds?
A stack of 20bb is a pivotal threshold. It is large enough to apply significant pressure (a 3-bet to about 5-6bb forces the opponent to risk their tournament life if they call or re-raise), yet small enough that the re-stealer is not pot-committed and can fold to a 4-bet without catastrophe. This stack size maximizes the chance that the original raiser folds, especially if they were opening with a wide range from late position.
Effective Usage
- Position: Typically used from the blinds or cutoff when the open raiser is in late position (cutoff or button) with a wide range.
- Hand Selection: Hands with good playability post-flop if called (e.g., suited connectors, small pairs) or blockers (e.g., A-x, K-x) are preferred. However, the primary weapon is fold equity, so any two cards can be considered if the situation is right.
- Opponent Tendencies: Most effective against tight-passive players who fold too often to aggression, or against aggressive openers who raise frequently but fold to re-raises.
Risks and Adjustments
- Calling Stations: Against opponents who rarely fold to 3-bets, restealing with weak hands becomes a trap. In such cases, tighten your range.
- Stack Sizes: If the opener has a stack covering yours, they may 4-bet more aggressively. Adjust by restealing less frequently or with stronger hands.
- ICM Considerations: In bubble or final table situations, ICM pressure can increase fold equity, making resteals more profitable. However, avoid restealing against short stacks who may be committed.
Example
A typical scenario: Blinds 500/1000 with ante. You have 20,000 chips (20bb) in the big blind. The button (with 30bb) opens to 2,500. You look down at 7♦6♦ and decide to 3-bet to 6,500. You risk 6,000 to win 4,000 (blinds+antes+open raise). If the button folds often enough (>60%), the play is profitable even if you lose every time called (assuming you seldom win post-flop).
In practice, 20bb resteals are a standard weapon in a tournament player's arsenal, enabling chip accumulation without needing a premium hand.
