Poker Term
CO位翻牌前双重下注（干牌面）（CO Preflop Double Barrel Dry）
Refers to an aggressive play where the player in the CO cutoff position raises preflop, then bets again on the flop, and the flop board texture is dry unlikely to form strong made hands.
Terminology Breakdown
- CO: Cut-off (the position immediately to the right of the button, a late position with positional advantage).
- Preflop Double Barrel: Here "Double Barrel" refers to two consecutive bets – typically the first barrel is a preflop raise and the second is a flop bet. Unlike the usual "Double Barrel" (flop + turn), this emphasizes that the first barrel begins preflop.
- Dry: The flop texture is dry, e.g., a rainbow board with no straight draw possibilities (e.g., K♠7♦2♣), making it unlikely to have hit a strong hand or a draw.
Strategic Implications
After a player in the CO position raises preflop, the flop is dry, and the opponent's range is less likely to have connected with a strong hand. Continuing to bet (the second barrel) can represent holding an overpair, top pair, or a stronger hand, forcing opponents to fold unimproved hands. Since a dry board typically offers few draws, the continuation bet has a high success rate.
Notes
- This play requires the player to have a wide raising range from the CO, and the opponent must perceive that range as strong.
- Adjust based on opponent type: it is more effective against tight-passive players, while loose-aggressive opponents may re-raise.
- If called on the flop, proceed cautiously on the turn, because on dry boards completed draws are rare – a call usually indicates the opponent has a strong hand or a medium pocket pair.
Common Scenario
Typical situation: CO raises with A♦J♠, flop comes K♠7♦2♣, player bets, representing strong hands like AK or KK, forcing opponents to fold unimproved hands such as QJ or AT.
