Poker Term
大盲位河牌乾燥牌面诈唬（BB River Bluff Dry）
A bluff bet or raise made by the big blind player on a dry board on the river.
Term Analysis
BB River Bluff Dry is a specific bluffing scenario in poker. "BB" refers to the Big Blind, "River" is the fifth community card, "Bluff" is deception, and "Dry" means the board lacks drawing possibilities (i.e., no obvious flush or straight draws).
Applicable Situations
- Position: The big blind player only posts the blind preflop but may hold weak hands entering the flop. On the river, if the board is very dry (e.g., flop K♠7♦2♣, turn 4♥, river 3♣), the opponent's range rarely contains made hands that can call. The big blind can exploit this by representing a strong hand and bluffing.
- Range Advantage: The big blind's defensive range is wider, often containing weak hands. However, on dry boards, the opponent's continuation betting range is also more polarized. The big blind can represent specific nut hands (e.g., top pair top kicker, sets, etc.).
Strategy Points
- Board Structure: Dry boards lack draws, so opponents are more likely to hold made hands or air. The big blind's bluff must make the opponent believe you hold a stronger hand than you actually do.
- Bet Sizing: Typically use larger bets (e.g., over 75% of the pot) to increase fold equity.
- Opponent Tendencies: Less effective against loose-passive players (who like to call); more effective against tight-aggressive players (who fold easily).
Common Mistakes
- Overuse: In multiway pots or against calling stations, bluffing on dry boards has lower success rates.
- Ignoring Preflop Action: If the preflop raiser has a strong range (e.g., AK or high pairs), bluffing on the river requires caution.
Example
- Flop: K♦9♠2♣ (dry)
- Turn: 5♥ (still dry)
- River: 7♠ (no draws)
- Big blind player bets pot, representing holding AK or a set, forcing an opponent (e.g., holding QJ) to fold.
