关煞位飘浮跟注（CO Float）
CO Float
In the cutoff CO, calling with marginal or air hands on the flop, planning to bluff or take the pot on the turn or river.
Overview
CO Float (Cutoff Float) is an advanced post-flop strategy commonly seen in No-Limit Texas Hold'em. The term "Float" originally means "to float," referring to calling a continuation bet on the flop with a weak hand while out of position, intending to overtake on later streets. CO Float specifically refers to a player executing this action while in the Cutoff position (CO, which is the first seat to the right of the button). Since the CO position has a relatively good positional advantage post-flop (only worse than the button) and usually faces opponents in the blinds or middle position, Float is more feasible.
Execution Conditions
- Opponent Characteristics: Opponent has a high flop continuation bet frequency but a high turn check frequency, meaning they may give up unimproved hands.
- Board Texture: The flop is dry (e.g., K♠7♥2♦). The opponent's raising range usually represents strong hands, but when a high card or draw completes on the turn, the opponent may reduce aggression.
- Hand Selection: Typically holding backdoor draws (e.g., two overcards, gutshot straight draws) or completely missing, but with blocking effects (e.g., holding key cards of the opponent's made hand).
Action Flow
- On the flop, the opponent bets, and the CO player calls (rather than raising or folding).
- On the turn, if the opponent checks, the CO player bets, attempting to force the opponent to fold. If the opponent continues betting, the CO usually folds.
- If the opponent checks the turn and the CO player bets but the opponent calls, the river action depends on whether the board improves to continue bluffing.
Strategic Considerations
- Frequency Control: Overusing Float can lead the opponent to adjust (e.g., continuing to bet or check-raising on the turn).
- Stack Depth: Suitable for deeper effective stacks (e.g., 100BB or more); Float is too risky with shallow stacks.
- Mind Games: If the opponent notices a Float tendency, they may call down with medium-strength hands, so balance is required.
Example
Assume a 6-handed table, effective stack 100BB. CO holds 8♠7♠, flop A♥9♦2♣. Opponent in BTN opened pre-flop, CO called. On the flop, BTN bets 2/3 pot. CO has air but believes the opponent's range is wide, so calls. Turn J♥, BTN checks, CO bets 3/4 pot, BTN folds. CO successfully steals the pot.
