Poker Term
河牌单调面四注（River 4-Bet on Monotone Board）
On the river with a monotone board, a player makes a fourth raise i.e., third re-raise.
Overview
River 4-Bet on Monotone Board is an extremely rare betting pattern in Texas Hold'em. Typically, a 4-bet occurs preflop (e.g., raise → 3-bet → 4-bet), but on the river, the maximum betting sequence is: bet, raise (2-bet), re-raise (3-bet), re-re-raise (4-bet). Therefore, a river 4-bet refers to the third raise (i.e., the fourth betting action) on the river.
Applicable Scenarios
- Monotone Board: All community cards are of the same suit, e.g., flop is three cards of the same suit, turn and river also remain the same suit. This makes a completed flush or a straight flush highly likely.
- Extremely Strong Hand: The player usually holds the nut flush or a straight flush and expects the opponent to re-raise multiple times.
Strategic Considerations
- Since a monotone board limits the opponent's possible bluffing ranges and value hands, a river 4-bet almost exclusively represents a very strong hand.
- In practice, river 4-bets are extremely rare; most players prefer to go all-in instead of raising incrementally.
- When facing a river 4-bet, it is almost always correct to fold unless you hold the nuts.
Notes
- This term is not a standard definition and may be interpreted differently among various player communities.
- In strategy discussions, it is advisable to specify the exact betting round to avoid confusion.
