HJ Fold to Check-Raise
HJ Fold to Check-Raise
The frequency with which the player in the Hijack position folds when facing a check-raise on the flop, turn, or river.
Definition
HJ Fold to Check-Raise is a poker statistic that measures how often a player in the Hijack (HJ) position folds after an opponent checks and then raises on the same street. It is expressed as a percentage and is commonly used in HUDs (Heads-Up Displays) for online cash games and tournaments.
Usage in Poker
The Hijack is the seat two positions to the right of the button (one seat to the right of the cutoff). A check-raise occurs when a player who checked earlier in the betting round later raises after another player bets. This stat tracks the HJ's response specifically when facing such a line.
A low fold percentage (e.g., under 30%) indicates a player who often calls or re-raises, potentially defending aggressively against check-raises. A high fold percentage (e.g., over 60%) suggests the HJ is easily pushed off hands, which check-raisers can exploit by raising more frequently. Both extremes offer exploitative opportunities.
Strategic Implications
In GTO (Game Theory Optimal) play, the HJ should have a balanced fold-to-check-raise frequency depending on board texture, stack sizes, and ranges. For example, on dry flops (e.g., K-7-2 rainbow), an HJ continuation bet might face a check-raise from the big blind with a polarized range. Folding too often loses equity, while calling or raising too loosely gives the opponent value.
Experienced players adjust their HJ Fold to Check-Raise based on opponent tendencies. Against a player who check-raises aggressively (high check-raise frequency), the HJ may call lighter or re-bluff. Against a passive opponent, folding marginal hands is safer.
Limitations
This stat is street-specific; a high flop fold percentage may not correlate with turn/river behavior. It also depends on stack depths and whether the check-raise is for value or as a bluff. Therefore, it should be used in conjunction with other stats like Check-Raise Frequency and Aggression Factor (AF).
