按钮位河牌双枪单调同花面（BTN River Double Barrel Monotone）
BTN River Double Barrel Monotone
On a monotone board, the button position player makes a second consecutive bet on the river usually having bet the flop, forming a double barrel betting pattern.
Term Breakdown
- BTN (Button): Button position, the dealer position, which is the most advantageous seat in Texas Hold’em, allowing last action post-flop.
- River: The final round of community cards.
- Double Barrel: Betting the flop and then betting the turn again, forming two consecutive bets. Here it is verbified to mean a second bet on the river.
- Monotone: All community cards are of the same suit, e.g., flop three of a suit, turn and river also of that suit.
Strategic Meaning
- This term describes an aggressive play: applying continuous pressure on a monotone board when holding a strong hand or bluffing.
- A monotone board makes opponents worry about a completed flush, so a double barrel (especially a river bet) can force opponents to fold marginal hands.
- Button position advantage: can observe opponents’ actions before deciding, making a river double barrel more effective.
Typical Scenario
- Flop Q♥9♥4♥, button holds K♥10♣ (top pair + straight draw) and bets; turn J♥, bets again; river 2♥ (flush completes). If opponent has been calling, a river bet represents a made flush, forcing opponent to fold one pair or weaker hands.
Notes
- This term is not standard common usage. The usual term is “Triple Barrel” for consecutive flop/turn/river bets. “Double Barrel” typically refers only to flop + turn.
