AFq from BTN

Meaning and Calculation

AFq (Aggression Frequency) is a poker HUD statistic that quantifies a player’s tendency to be aggressive rather than passive. It is calculated as:

AFq = (Number of aggressive actions) / (Number of aggressive + passive actions) × 100%

where aggressive actions include bets and raises (including re-raises), and passive actions include calls and checks. Only hands where the player has an opportunity to be aggressive are considered (i.e., they are not all-in or facing an all-in).

When specified as "from BTN," it filters the statistic to only those hands where the player is sitting on the dealer button. This removes positional bias, allowing a more precise read of how aggressive a player is with positional advantage.

Typical AFq Values on the Button

• Low AFq (below 40%): The player is predominantly passive on the button. They call or check often, rarely raising or betting. Such players may be vulnerable to steals and frequent c-bets.
• Medium AFq (40%–60%): Balanced aggression. The player raises or bets a moderate portion of the time, mixing in calls and checks appropriately.
• High AFq (over 60%): Very aggressive on the button. They raise or bet most opportunities, indicating a tendency to exploit position with frequent opens, continuation bets, and bluffs.

Note that AFq is highly dependent on opponent style, table dynamics, and stack sizes. A high AFq does not automatically imply a winning strategy; it must be combined with good hand selection (VPIP) and post-flop skills.

Strategic Implications

• Against a player with high AFq from BTN, you can expect them to raise a wide range preflop and continue aggressively post-flop. Consider re-stealing (3-betting) more often and floating with strong draws or medium hands to trap.
• Against a low AFq from BTN, the player is likely to have a stronger range when they do raise or bet, as they are passive with weaker holdings. You can overfold to their aggression and widen your own opening range to exploit their passivity.
• For your own play, monitoring AFq from BTN helps ensure you are not too predictable. Aim for a balanced frequency that keeps opponents guessing, generally around 50%–60% for a solid aggressive approach.

Limitations

AFq does not distinguish between bet sizes or the strength of hands. A player could have high AFq but always bet small with mediocre hands, or large only with value. It also ignores timing and board texture. Therefore, AFq should be used alongside other stats like PFR (preflop raise), CBet (continuation bet), and WTSD (went to showdown) for a fuller picture.

The "from BTN" filter reduces sample size, so ensure you have enough hands (e.g., 50+) for statistical relevance before drawing strong conclusions.
