干燥牌面河牌漂浮（River Float on Dry Board）

Concept

River Float on Dry Board is a bluffing strategy in poker, specifically on the river in a dry board (i.e., a board with no possible straight or flush draws, such as a rainbow board with unconnected ranks). The player raises to represent a strong hand, forcing the opponent to fold a better hand.

Strategic Logic

• A dry board means most draws have missed on the river, so the opponent's betting range typically consists of made hands or marginal value hands.
• The player exploits this by raising the opponent's river bet, making the opponent believe they have hit a hidden strong hand (e.g., a set or two pair), thus inducing a fold from medium-strength pairs or top pairs.
• The effectiveness of this strategy depends on the opponent's folding tendencies and range perception. It is often used against tight-passive players who tend to over-fold to river raises.

Considerations

• River float should be used cautiously as it is a high-risk bluff.
• Evaluate board texture, opponent's range, and stack depths.
• The strategy may fail against calling stations or opponents with strong bluff-catching abilities.

Example

• Board: A♠9♣4♦ 2♥ 7♦ (dry, no straight or flush possible).
• Both players check flop and turn. On the river, opponent bets half-pot. Player holds 8♠5♠ (air) and raises to 2.5x, opponent folds.
