CO位河牌成对牌面诈唬（CO River Bluff Paired）
Refers to a bluffing action taken by a player in the CO cutoff position on the river when facing a paired board.
Overview
CO (Cutoff) is the position immediately to the right of the button, offering positional advantage. River Bluff Paired refers specifically to a bluff initiated by the CO player on the river when the board is paired (i.e., at least one pair is present on the board).
Strategic Background
- A paired board reduces opponents' drawing possibilities, as straight and flush draws may already be blocked, but it also increases the probability that opponents hold strong hands like full houses or quads.
- The CO may have established a certain range image on the flop and turn, so a river bluff must align with the previous action line.
- Typical scenario: The CO player c-bets on the flop, checks or bets on the turn, and when the river pairs, the player bets to represent having made trips or a full house, forcing opponents to fold medium-strength hands (e.g., top pair).
Considerations
- Bluff success depends on opponents' interpretation of the paired board and their folding tendencies.
- If an opponent's range contains many calling or all-in hands (e.g., trips or better), the bluff carries higher risk.
- Frequent bluffing should be avoided on boards that clearly favor opponents' value hands (e.g., high pairs, paired boards where draws missed).
