按钮位河牌双枪彩虹面（BTN River Double Barrel Rainbow）
BTN River Double Barrel Rainbow
Refers to a strategy where the player on the button bets on a rainbow flop first barrel, checks the turn, and then bets again on the river second barrel.
Term Explanation
BTN River Double Barrel Rainbow is a compound poker term used to describe a specific betting pattern and board structure. It consists of the following components:
- BTN: Button, the dealer position, one of the most advantageous positions in the game, acting last post-flop.
- River: The final community card street.
- Double Barrel: Typically refers to consecutive bets on two streets, but here it specifically means betting on the flop, then skipping the turn and betting again on the river.
- Rainbow: The flop contains three cards of different suits, eliminating any flush draw possibility.
Strategic Context
This line is commonly used after a flop C-bet when the turn card is unfavorable for your range or cannot be continued (e.g., a high card or a card that completes a draw), leading to a check. On the river, if your hand strength improves or you judge your opponent has a high fold rate, you bet again, creating two bets (first on the flop, second on the river). This line balances value betting and bluffing while leveraging the informational advantage of the button position.
Typical Scenarios
- Value Bet: Betting top pair on the flop, checking the turn to control the pot, then betting again on a safe river to extract thin value.
- Bluff: Bluffing with a draw or air on the flop, checking the turn to show weakness, then attacking again on the river when the opponent shows weakness.
The rainbow board reduces the possibility of flush draws, making river betting more focused on attacking holdings like pairs and straights. This term is often used in advanced strategy discussions, emphasizing the interplay between position and betting rhythm.
