关煞位河牌单调面挤压（CO River Squeeze Monotone）
Refers to a strategy where a player in the cutoff CO makes a large raise squeeze on the river when facing a monotone board, aiming to force opponents to fold or to extract value.
Term Breakdown
- CO (Cutoff): The position to the immediate right of the dealer button, considered a late position and usually enjoying a wide range advantage.
- River: The final betting round where all community cards are dealt.
- Squeeze: Originally refers to a re-raise preflop or postflop facing a bet and a call. Here it is extended to mean a large raise on the river intended to apply maximum pressure.
- Monotone: Refers to a board where three or more cards are all of the same suit (e.g., A♠ K♠ 7♠ 2♠), making flush completion highly likely.
Strategy Background
On a monotone board at the river, an opponent may hold a flush, a flush draw, or have completely missed. As the CO player, if your range contains some flushes and many bluff combinations, you can represent the nut flush by making a large raise (squeeze), forcing opponents to fold medium-strength hands (e.g., top pair) or even smaller flushes. This strategy typically requires weighing the opponent's calling tendency and pot odds.
Applicable Conditions
- The opponent's range has a low proportion of flush combinations or has been eliminated (e.g., they bet the flop but did not continue on the turn).
- Your own image is aggressive, allowing you to credibly represent a very strong hand.
- The board structure allows for bluffs (e.g., having high cards, straight draw blockers, etc.).
Example
In a 2-5 No-Limit Hold'em game, the board is A♥ K♥ 7♥ 2♥. You hold Q♥ J♣. On the river, your opponent bets. You raise 3x, representing the nut flush with A♥ or K♥.
Notes
This term is not a standard poker term; it is more of an abbreviation used by specific coaches or in certain articles. In practice, you must adjust based on your opponent's tendencies and stack depth.
