河牌湿润牌面四注（River 4-Bet on Wet Board）
A fourth bet i.e., third raise made on the river, and the board is very wet multiple draws or made straights/flushes.
Overview
River 4-Bet on Wet Board is an advanced poker term referring to a fourth raise (i.e., a re-raise after an initial bet, a raise, and another raise) on the river when the board texture is wet (e.g., connected cards, flush draws, etc.). The term borrows the concept of a "4-bet" from preflop play, but since postflop raises are not commonly numbered, this term is mostly used in strategic discussions or among high-level players.
Typical Scenario
On the river, if the board is wet—such as a flush or straight possible—Player A bets, Player B raises, Player A re-raises (i.e., a 3-bet), and then Player B raises again, that constitutes a 4-bet. This action typically represents a very strong made hand or a carefully constructed bluff, as both players' ranges on a wet board may include many draws or made hands.
Strategic Significance
- Value Raise: When holding the nuts or close to it (e.g., top full house, straight flush), a 4-bet extracts maximum value, especially if the opponent may hold a strong second-best hand.
- Bluff Raise: In extreme cases, a player can represent an ultra-strong hand to force the opponent to fold medium-strength made hands (e.g., two pair, trips). This requires precise range reading and carries high risk.
The complexity of wet boards requires players to balance their 4-bet range to avoid being easily exploited by observant opponents.
Notes
- This term is not a standard poker term; definitions may vary among players or in different literature. Context should be considered when using it.
- In actual play, most poker rooms limit the number of postflop raises (e.g., one initial raise plus three re-raises maximum), so a 4-bet may be subject to house rules.
