BB Fold to Check-Raise

Overview

BB Fold to Check-Raise is a poker statistic that measures how often the player in the Big Blind (BB) folds after a check-raise when they were the pre-flop caller. It is commonly abbreviated as BB Fold to C/R or BB F2C/R in tracking software like PokerTracker 4 or Hold'em Manager 3.

Definition and Calculation

The stat is calculated as:

• Numerator: Times BB folded to a check-raise
• Denominator: Total opportunities BB faced a check-raise (including folds, calls, and reraises)

It is expressed as a percentage. For example, a value of 45% means that nearly half the time the BB folds when checked to and then raised by an opponent.

Usage in HUDs

This stat is part of a suite of defensive statistics for the Big Blind position. It helps assess how the BB responds to aggression after checking. A high fold rate may indicate that the BB is overfolding to check-raises, making them exploitable by players who frequently check-raise. A low fold rate suggests the BB is sticky or aggressive, often calling or reraising.

Typical Values and Interpretation

• Low (0–30%): The BB rarely folds to check-raises. This often indicates a player who defends their check range strongly, possibly with many strong hands or draws.
• Medium (30–50%): A balanced range. Many regs fall here, adjusting based on board texture and opponent tendencies.
• High (50%+): The BB folds often. This can be exploited by check-raising more frequently, especially on boards that favor the aggressor.

Strategic Implications

• Exploiting High Fold Rates: If an opponent has a high BB Fold to Check-Raise, you can increase your check-raise frequency on flops where you have range advantage. This puts pressure on their capped range.
• Adjusting Against Low Fold Rates: Against sticky opponents, check-raise for value with strong hands and use smaller sizing. They may call too wide, so value betting is key.
• Sample Size Considerations: This stat stabilizes around 500+ opportunities. Small samples are unreliable. Also, note that it is situational: board texture, stack depth, and opponent tendencies matter.

Related Terms

• Check-Raise: Raising after an opponent checks.
• BB Call to Check-Raise: The complement (calls + reraises).
• Fold to C-Bet: Similar but not specific to check-raise.
• Check-Raise Frequency: How often a player check-raises.

Conclusion

BB Fold to Check-Raise is a useful tool for post-flop analysis, especially in heads-up or blind-vs-blind situations. Combined with other stats, it helps build a comprehensive profile of an opponent's tendencies. Use it with caution on small samples and adjust based on dynamic factors.
