15bb Steal
15bb Steal
A preflop raise aimed at stealing the blinds and antes when the effective stack size is approximately 15 big blinds, often executed as an all-in or a min-raise.
Overview
A 15bb Steal refers to a preflop raise (or shove) from a player with an effective stack of around 15 big blinds, intended to win the blinds and antes without contest. At this stack depth, the raiser is typically short-stacked and cannot afford to play many flops, so stealing becomes a crucial part of tournament or cash game survival. The most common options are a min-raise (to 2bb) or a direct all-in, with the latter often preferred because it denies opponents the chance to re-steal and simplifies postflop decisions.
Typical Scenarios
- Late position (cutoff, button, or small blind): Players with 15bb are more likely to steal from late position because they have fewer opponents behind them.
- Fold equity: A 15bb shove puts significant pressure on the blinds, especially if they have similar or smaller stacks. The big blind must call with a wider range than usual, but many hands are still folds.
- Ante effect: In tournaments with antes, the pot (blinds + antes) can be large relative to stack size, making a steal more profitable even with marginal hands.
Strategy Considerations
- Hand selection: Typically, suited connectors, weak aces, and small pairs are used for stealing because they have decent equity against calling ranges. However, at 15bb, the recommended shoving range from the button or small blind often includes any two cards if opponents are tight.
- Opponent tendencies: Against loose callers, tighten the stealing range; against tight players, steal wider. Players in the big blind with 15bb might defend with a wide range (e.g., any two cards) to prevent exploitation.
- Re-steal risk: If a player min-raises to 2bb and the big blind shoves, the original raiser must have a hand strong enough to call (usually top 25-30% of hands). Many players prefer open-shoving to avoid this tough decision.
Example
In a tournament with blinds 500/1000 and ante 100, a player on the button with 15,000 chips (15bb) sees everyone fold to him. He holds 9♠7♠. A min-raise to 2,000 risks 2bb to win 1,800 (blinds+antes). If the big blind is tight, this is profitable. Alternatively, an all-in of 15,000 might also be profitable if opponents fold often enough.
