Poker Term
关位翻牌前加注后同花面三连注（CO Preflop Triple Barrel Monotone）
Refers to an aggressive play where after raising preflop from the cutoff CO, the player makes a triple-barrel bet on the flop, turn, and river when the board is monotone same suit.
Term Composition
This term is composed of four parts:
- CO (Cut Off) – The position to the right of the button, usually with post-flop position advantage.
- Preflop – The action phase before the flop.
- Triple Barrel – Continuously betting on the flop, turn, and river (also known as three streets).
- Monotone – All community cards are of the same suit (e.g., ♠♠♠), making flushes very easy to form.
Strategic Meaning
This play typically represents holding a strong hand (such as top pair or better preflop, or a flush draw) or as a pure bluff. On a monotone board, the opponent's calling range is limited to flush draws, middle pairs, etc., and a continued bet can force the opponent to fold some marginal hands.
Typical Scenario
- The cutoff player raises preflop, and the big blind calls.
- Flop: all hearts (♥♥♥).
- The cutoff player bets about 2/3 pot on the flop, about 3/4 pot on the turn, and bets pot or more on the river.
Notes
- Monotone boards easily make flushes; if the opponent holds a flush, the triple barrel may face a raise.
- The preflop raiser's range usually contains many high cards; on a monotone board without a flush draw or made hand, the triple barrel carries higher risk.
- This term is not a standard poker term; it is more of a descriptive combination and is rarely used alone in actual communication.
