CO位25bb跟注（CO 25bb Call Off）

Term Explanation

CO 25bb Call Off is a common strategic shorthand in tournaments or cash games, combining position, stack depth, and action type.

• CO (Cut Off): The position to the right of the button, with a relatively favorable postflop position.
• 25bb: A stack of approximately 25 big blinds, considered medium depth. At this stack size, the player has some room to call but also faces elimination risk.
• Call Off: Refers to calling an opponent's raise or all-in with no intention of re-raising, usually meaning the player is prepared to go to showdown without further aggression.

Typical Scenario

In the mid-stage of a tournament, the CO player holds 25bb, and an early position player (20bb stack) shoves all-in. If the CO believes the opponent's range is wide and their own hand has sufficient showdown value, they can Call Off without re-raising. This is a solid play leveraging positional advantage and favorable odds.

Strategic Points

• Range Construction: Typically uses medium pairs, suited connectors, or Ax suited to combat the opponent's shoving range, avoiding calling with weak hands.
• ICM Considerations: Near the bubble or final table, Call Off must account for ICM pressure to avoid losing tournament value due to a low-probability elimination.
• Opponent Tendencies: If the opponent's shoving range is tight, tighten your Call Off range; if loose, you can widen it accordingly.

Notes

• "Call Off" is not the same as "catching a bluff"; it emphasizes passive calling with a certain range in a favorable position rather than active bluffing.
• 25bb is a common threshold; below 20bb, the Call Off range should be more aggressive; above 30bb, it may shift to re-raising.
