CO位75bb偷盲（CO 75bb Steal）

Term Explanation

CO 75bb Steal refers to an action in Texas Hold'em cash games or tournaments where a player in the CO (Cutoff, to the right of the button) position, with an effective stack depth of approximately 75 big blinds, raises in an attempt to steal the blinds.

Importance of Position and Stack Depth

The CO position is one of the most advantageous preflop positions: it acts before the button but has more information than players in earlier positions, observing more opponents' folds. With a stack depth of 75bb, which is moderately deep, players can still flexibly use various raise sizes, and opponents' defending ranges will be affected.

Steal Strategy Considerations

• Raise Size: Typical range is 2.2 to 3 big blinds. At 75bb depth, raising to around 2.5bb is common, giving opponents reasonable pot odds while controlling risk.
• Stealing Range: Usually includes a wide range such as small pairs, suited connectors, weak Aces, etc., leveraging position to play postflop.
• Opponent Adjustments: If the blinds have a high fold rate, increase steal frequency; conversely, if opponents call or 3-bet frequently, tighten the range and consider 4-betting or folding.

Risks and Rewards

Successfully stealing wins 1.5bb (blinds and antes). However, at 75bb depth, being called or re-raised may lead to unfavorable postflop situations. Decisions should be based on opponent tendencies, table dynamics, and range balance.

Example: In a 6-handed game with blinds 100/200 (no ante), effective stack 15,000. CO holds 78s (suited connectors) and opens to 500 (2.5bb), attempting to steal. If both blinds fold, profit is 300; if called, postflop play leverages position and drawing potential.
