偷盲（blind steal）

Overview

Blind stealing is an important aggressive strategy in Texas Hold'em, typically occurring when action folds to the button or cutoff (CO). The player raises (usually 2.5-3 times the big blind) to pressure the small and big blinds, leveraging their fold equity to win the pot uncontested. The success of a steal depends on the tightness/weakness of the blind players, table image, and stack depth.

Applicable Scenarios

• Positional Advantage: The button and cutoff are the best positions for stealing, as they act later and have more information.
• Tight/Weak Blind Players: If the small and big blinds fold frequently (e.g., preflop fold rate above 70%), stealing is profitable.
• Marginal Hand Strength: Even with marginal hands like A-7, K-10, suited connectors, etc., a steal attempt can be viable.
• Healthy Stack: Stealing is safer with deep stacks; short stacks require caution, as they are vulnerable to re-raise all-ins.

Risks and Adjustments

• Re-steal: The blinds may re-raise with strong hands or as a bluff. The stealer must assess the situation and avoid blindly continuing.
• Frequency Balance: Stealing too often allows opponents to exploitatively re-raise. Therefore, mix in genuine value hands.
• Opponent Reads: Against loose-aggressive players (high re-steal rate), reduce stealing or trap with strong hands.

Mathematical Basis

The breakeven point of a steal depends on the raise size and fold equity. For example: a standard steal raise to 3 big blinds (BB) with a pot of 1.5 BB requires a fold rate of at least (3 / (3+1.5)) = 66.7% to show immediate profit. In practice, subsequent action (re-raises or calls) must also be considered.

Example

Assume blinds are 10/20 with effective stacks of 2000. The button folds, and the cutoff raises to 60 with 7-8 suited. The big blind folds, the small blind folds, and the cutoff wins the 30 pot. This is a typical blind steal.
