河牌圈成对面上的第五次加注（River 5-Bet on Paired Board）
On the river, after the pot has been raised four times, the player makes a fifth bet, and the board is paired.
Term Background
This term describes an extremely rare Texas Hold'em scenario, typically occurring in deep-stacked, highly aggressive games. "River" refers to the river betting round, and "Paired Board" means the community cards contain at least one pair (e.g., a pair formed on the flop or turn). "5-Bet" indicates that four raises have already occurred in the betting round (e.g., bet, raise, re-raise, 3-bet, 4-bet; the fifth action is a 5-bet). This scenario usually implies either extreme strength or a pure bluff, as the more raises in a single pot, the more polarized the range becomes.
Strategic Implications
On a paired board, a river 5-bet almost exclusively arises in the following situations:
- The player holds a full house or four-of-a-kind (especially when the river completes their full house).
- The player converts a draw or medium-strength hand into a bluff, attempting to force an opponent to fold a stronger made hand (such as trips or a straight).
Given the high number of raises, the bluffing percentage is typically extremely low, since the opponent's calling range after a 4-bet is already quite strong. In actual play, river 5-bets are very rare and are more often discussed in theory.
Notes
This term is not commonly found in mainstream poker literature; it is mostly used by advanced players when analyzing complex pots. In real games, most 5-bets occur preflop rather than on the river.
