Poker Term
CO位河牌圈4-Bet湿牌面（CO River 4-Bet Wet）
A fourth raise i.e., a re-re-raise from the CO position on the river with a wet board many draws.
Term Overview
"CO River 4-Bet Wet" is not a standard poker term; it may be a combined usage. Typically, "4-Bet" refers to the fourth raise preflop, whereas on the river the betting rounds are limited to: bet, raise, re-raise — "4-Bet" is rarely used to describe a river action. If interpreted loosely, it means a player in the Cutoff position re-raises (i.e., the fourth betting action) on the river after facing an opponent's raise, on a wet board (e.g., possible straights or flush draws).
Strategic Implications
- This scenario is very rare, as the river usually only allows up to three betting opportunities unless multiple bets have already occurred.
- On a wet board, a 4-Bet often indicates a very strong made hand (e.g., full house, straight flush) or a bluff disguised as a strong hand.
- Players must be cautious, as a 4-Bet on the river creates a massive pot, and the opponent's range is typically polarized.
Important Notes
This term is rarely used in formal poker literature or discussions. It is recommended to replace it with the standard expression "river re-raise".
