HJ AFq

HJ AFq (Hijack Aggression Frequency)

Definition HJ AFq is a player-specific statistic used in online poker tracking software (e.g., PokerTracker, Hold'em Manager) that measures how often a player in the hijack position (the seat two to the right of the button, also called UTG+1 in 6-max) makes an aggressive action (bet or raise) when given the chance. It is expressed as a percentage and calculated as:

Number of aggressive actions (bet + raise) / (Number of aggressive actions + number of passive actions (call + check)) × 100

Only situations where the player could choose to be aggressive or passive are counted; folds are excluded.

Purpose and Usage

AFq is a more refined metric than standard aggression factor (AF) because it accounts for the frequency of aggression rather than the ratio. A high HJ AFq indicates a player who frequently bets or raises when in the hijack, suggesting an aggressive style that may include wide opening ranges, frequent continuation bets, or bluff raises. A low AFq implies a passive approach, often checking or calling instead of betting or raising.

In practice, players use HJ AFq to identify tendencies:

• High HJ AFq (e.g., >60%): Opponent likely raises many hands from HJ, continuation bets often, and may be exploitable with check-raises or re-raises.
• Low HJ AFq (e.g., <35%): Opponent tends to limp, call, or check; they may be weak-tight or set-mining; can be pressured with frequent bets.

Typical Values and Interpretation

Typical HJ AFq values vary by stake and player pool, but common benchmarks for 6-max cash games:

• Tight-aggressive (TAG): ~45-55%
• Loose-aggressive (LAG): ~55-65%
• Passive fish: ~25-35%

However, sample size matters: AFq stabilizes after several hundred hands. A high AFq from a small sample (e.g., 50 hands) may be misleading.

Example

Suppose in 100 hands logged, a player in HJ has 80 opportunities to be aggressive (i.e., they faced a situation where betting/raising or checking/calling is possible). If they bet or raised in 32 of those spots, their HJ AFq is (32/80) × 100 = 40%.

Related Concepts

• Aggression Frequency (AFq) vs. Aggression Factor (AF): AF = (bet + raise) / call; AFq includes checks in passive actions, making it a percentage of aggressive decisions.
• Positional Stats: HJ AFq is often compared to CO (cutoff) or BTN (button) AFq to assess positional awareness.

Limitations

AFq alone does not indicate hand strength or context (e.g., number of opponents, board texture). Combining with other stats like VPIP, PFR, and fold-to-c-bet gives a more complete profile. Additionally, AFq is less meaningful in pot-limit or no-limit games where aggression frequency can be manipulated with small bets.
