Fold to 4-Bet from HJ

Overview

Fold to 4-Bet from HJ is a poker tracking statistic that measures how often a player folds to a 4-bet after opening from the hijack position. It is typically expressed as a percentage. This stat is commonly used in online cash games and tournaments to analyze a player's preflop tendencies, particularly their willingness to continue against aggression after raising from a late-middle position.

Calculation

The stat is calculated as: (Number of times player folded to a 4-bet when opening from HJ) / (Total number of times player faced a 4-bet after opening from HJ). The sample size should be large enough to be meaningful (e.g., at least 50-100 opportunities). Note that the stat only counts hands where the player opened from HJ and then faced a 4-bet; it does not include situations where the player faced a 3-bet and then folded, or where they faced a 4-bet after calling a 3-bet.

Interpretation

A low Fold to 4-Bet from HJ (e.g., below 30%) indicates that the player tends to call or raise against 4-bets frequently, suggesting a strong range or a willingness to play big pots. A high stat (e.g., above 60%) suggests the player is often folding to 4-bets, meaning they are opening a wider range from HJ but are reluctant to commit further when faced with a 4-bet. The exact thresholds depend on the game type (e.g., cash games vs. tournaments) and the opponent's tendencies.

Strategic Implications

• Against a low fold to 4-bet: Opponents are less likely to fold to 4-bets, so 3-betting from the blinds or later positions should be done with a balanced range. Light 4-betting may be less profitable if the HJ player continues frequently.
• Against a high fold to 4-bet: This indicates that the HJ player is folding a large portion of their opening range. Aggressive players can exploit this by 3-betting more frequently, knowing the HJ will often fold. However, if the HJ player is also folding to 3-bets, then 3-betting becomes even more profitable.
• Adjusting your own play: If your Fold to 4-Bet from HJ is too high, you may be exploitable. Consider either tightening your opening range from HJ or being more willing to call/5-bet with certain hands (e.g., strong pairs, suited connectors) to defend against 3-bets. Conversely, if it is too low, you may be calling 4-bets too light, which can lead to large losses against tight opponents.

Related Concepts

• Hijack (HJ): The position two seats to the right of the button (or one seat to the right of the cutoff). It is a late-middle position with moderate stealing opportunities.
• 3-Bet: A re-raise after an initial raise (e.g., open-raise from HJ).
• 4-Bet: A re-raise after a 3-bet. Typically a 4-bet indicates a very strong hand or a bluff.
• Fold to 3-Bet: Another stat measuring how often a player folds to a 3-bet after opening. Both stats together give a fuller picture of preflop strategy.
• Range: The set of hands a player is likely to have in a given situation.

Limitations

Fold to 4-Bet from HJ should not be used in isolation. Sample size, opponent tendencies, and stack depths affect the reliability. In tournament play, ICM considerations can alter optimal behavior. Also, the stat may be affected by the player's own 4-betting range and their willingness to 5-bet. Always consider the full context when making decisions based on this stat.
