CO河牌湿润牌面驴式下注（CO River Donk Bet Wet）

Term Analysis

CO River Donk Bet Wet is a compound term describing a specific betting pattern on the river: a player in the CO (Cutoff, the seat to the right of the button) who called a raise preflop, then leads out with a bet on a wet river board (i.e., a board with multiple drawing or made hand possibilities) against the preflop raiser. This bet is called a "Donk Bet," which typically refers to an out-of-position player leading into the raiser, but here it specifically refers to the CO on the river. Although the CO usually has positional advantage, if the preflop raiser is first to act on the river (e.g., the preflop raiser is in the blinds or early position) and checks, then the CO's bet is still an aggressive lead, hence called a Donk Bet.

Strategic Considerations

This bet is typically used in the following scenarios:

• Value Bet: The CO believes their hand is strong enough on a wet board to extract value from the preflop raiser's calling range, especially when the river completes their draw.
• Blocking Bet: The CO may have a medium-strength hand and wants to see a showdown cheaply, avoiding a large bet from the opponent.
• Bluff: The CO may use the wet board to represent a made strong hand, forcing the opponent to fold.

Wet boards are characterized by multiple drawing possibilities, such as flush draws, straight draws, or flushes. The preflop raiser may have a continuing range on the river (e.g., top pair, draws, etc.) that will call, so the CO needs to carefully assess the opponent's tendencies and their own hand strength.

Notes

This bet is relatively rare in practice because the CO usually has positional advantage and would prefer to bet after the preflop raiser checks. However, if the CO has called on the flop and turn, then suddenly leads out on the river, it often signifies that their hand has improved. Opponents should be wary of potential value bets or bluffs.
