小盲10bb偷盲（SB 10bb Steal）
SB 10bb Steal
A strategy where the small blind player attempts to steal the blinds and dead money in the pot by raising when the effective stack is approximately 10 big blinds.
Concept and Applicable Scenarios
SB 10bb Steal is an aggressive strategy commonly seen in the deep-stack preflop stage, typically appearing in late tournament phases or short-stack cash game situations. At this point, the small blind has a stack depth of about 10 big blinds (~10bb), and the main goal of raising is to steal the big blind's chips as well as the dead money in the pot. Since the big blind may not have a strong hand or may be unwilling to risk their short stack, the small blind's steal success rate is relatively high.
Action and Stack Dynamics
- Raise sizing: Usually raise to 2-2.5bb, and in rare cases up to 3bb. Raising too large (e.g., over 3.5bb) reduces the profitability of the steal, as a higher success rate is required to be profitable.
- Range selection: The stealing range should include many weak hands (e.g., low suited connectors, small pairs, weak Ax), while mixing in a few strong hands (e.g., AA/KK) for balance. It is not recommended to frequently steal with medium-strength hands (e.g., KQo), as they are difficult to handle when re-raised.
- Response to re-steals: If the big blind shoves, the small blind must decide whether to call or fold based on pot odds and hand strength. Generally, about 30-40% of the stealing range (e.g., Ax, pairs, strong suited connectors) can call the all-in.
Strategy Adjustments
- Against tight-passive players: Increase steal frequency to about 70%.
- Against aggressive players: Decrease steal frequency, raise mostly with strong hands, and be prepared to fold.
- Blind level changes: As blinds increase, the profit margin for steals shrinks, requiring a stricter range selection.
Common Misconceptions
- Misconception 1: Always raise to 2.5bb when stealing with 10bb. In reality, adjust based on opponent history.
- Misconception 2: Stealing only involves weak hands. A balanced steal range needs strong hands to prevent counter-steals.
Example (Typical Situation)
Effective stack 9.5bb. Small blind hand 87s, raise to 2.2bb. Big blind folds, small blind successfully takes 1.5bb of dead money.
