SB Fold to Check-Raise

Meaning and Calculation

SB Fold to Check-Raise is a statistic for the small blind (SB) that measures how often the SB folds when facing a check-raise after betting or raising on the flop or turn. It is usually expressed as a percentage and calculated as: Number of folds / Total number of check-raise situations × 100%.

Application Scenarios

This statistic is mainly used to evaluate how defensively a small blind player reacts to a check-raise. For example, if the SB makes a continuation bet (c-bet) on the flop and the big blind check-raises, the SB's response (fold, call, or raise) is recorded. A high fold rate (e.g., over 60%) suggests the SB is vulnerable to check-raise bluffs, while a low fold rate indicates tighter defense, possibly holding a strong hand or willing to call.

Strategic Significance

• Against opponents with a high fold rate: Players in the big blind or other positions can frequently use a check-raise strategy to exploit the SB's folding tendency and steal the pot, especially when the SB's range is wide.
• Against opponents with a low fold rate: When check-raising, lean towards value hands (such as top pair or better) to avoid being called or re-raised.
• Adjustment for the SB: If this statistic is too high, the SB should reduce the frequency of continuation bets on the flop, or use more hands to call or raise when facing a check-raise, in order to protect their range.

Notes

This statistic requires a sufficient sample size (at least 100 encounters) to be statistically meaningful. Additionally, different board textures (e.g., dry vs. wet) can affect the opponent's check-raising range, so it should be analyzed in context.
