按钮位河牌干燥面过牌弃牌（BTN River Check-Fold Dry）

Meaning

BTN River Check-Fold Dry is a passive strategy in Texas Hold'em for the late position (button) facing a dry river board. After raising preflop and possibly continuation betting on the flop and turn, on the river if the board is dry (e.g., rainbow with no straight or flush possibilities) and the opponent bets after the player checks, the player folds.

Applicable Scenarios

• Dry Board: The community cards have no obvious drawing possibilities, e.g., flop K♠7♦2♣, turn 4♥, river 3♠. Opponents typically can only win the pot with made hands.
• Opponent Range: After calling on the flop and turn, the opponent's river bet usually represents a strong made hand, making the player's one pair or medium-strength hand difficult to call.
• Range Disadvantage: As the preflop raiser, the player typically represents high cards or pairs on dry boards, but after consecutive bets, the range may weaken; the opponent's call to the river and subsequent bet indicates a stronger range.

Strategic Reasons

• Avoid Value Betting: On dry boards, betting is unlikely to be called by worse hands and may instead be raised by better hands.
• Control the Pot: Checking on the river controls the pot size and prevents overcommitting chips.
• Exploitative Consideration: If the opponent rarely bluffs on dry boards, check-folding avoids losses from being bluffed.

Notes

• This strategy is not suitable for wet boards or against opponents with aggressive bluffing tendencies.
• Players should adjust based on opponent data and historical behavior to avoid being exploited by over-folding.
