CO Fold to Check-Raise

Overview

CO Fold to Check-Raise is a poker HUD statistic that tracks how often a player in the cutoff position (CO) folds after they have made a bet and then face a check-raise from an opponent. The stat is typically expressed as a percentage and is calculated per street (flop, turn, river) or as an overall figure. It is a measure of a player's tendency to give up on their hand when faced with aggression from a check-raiser.

Interpretation

A high CO Fold to Check-Raise (e.g., >60%) indicates that the player frequently folds when check-raised, suggesting they are often betting with weak holdings or are easily pushed off hands. This can be exploited by aggressive opponents who can profitably check-raise more often. Conversely, a low percentage (e.g., <30%) suggests the player is sticky or calls down with marginal hands, making check-raises less effective against them.

Note that this stat should be used in context of sample size and opponent tendencies. A single occurrence may not be reliable. Also, the stat is most meaningful when the opponent's check-raising range is known or when the player is bet-folding too much.

Usage in Strategy

When analyzing a fish or a regular, this stat helps in adjusting your own check-raising frequency. Against a player with a high CO Fold to Check-Raise, you can increase your check-raise bluffs on boards that favor your range. Against a low fold-to-check-raise opponent, you should value check-raise more and bluff less.

Example

• Situation: You are in the big blind versus a cutoff open-raiser. The flop comes K♠7♦2♣. You check, CO bets 75% pot. You check-raise to 2.5x his bet.
• If CO's Fold to Check-Raise is 70%: He is likely to fold many weak kings and draws, so your semi-bluff with a gutshot is profitable.
• If CO's Fold to Check-Raise is 25%: He will often call or reraise, so you should only check-raise with strong value hands.

Limitations

• This stat does not differentiate between check-raises for value versus bluffs. A high fold frequency could mean the player is correctly folding against strong ranges.
• Sample size matters; a few incidents can skew the percentage.
• The stat is position-specific (CO only). Similar stats exist for other positions (e.g., BTN Fold to Check-Raise).

Conclusion

CO Fold to Check-Raise is a useful stat for gauging how easily a cutoff player is pushed off their bet. It helps inform your decision to check-raise as a bluff or for value, but should always be considered alongside other reads and board texture.
