BTN AFq

Overview

BTN AFq is a poker statistic used to measure a player's aggression from the Button position. AFq stands for Aggression Frequency, and its formula is: (Bets + Raises) / (Bets + Raises + Calls + Folds). Note that checks are not included in the calculation, so AFq only reflects the tendency to voluntarily put chips into the pot.

Interpretation and Application

• High BTN AFq (e.g., > 70%): Indicates a player is extremely aggressive on the Button, frequently betting or raising and rarely calling or folding. Such players often try to leverage positional advantage to apply constant pressure, but may over-bluff or have an overly wide value range.
• Medium BTN AFq (approximately 40%–70%): A balanced aggressive style that adjusts based on board texture and opponents. These players have strong exploitative ability from the Button.
• Low BTN AFq (e.g., < 40%): Suggests a passive tendency on the Button, preferring to check or call. This may stem from fear of variance or a preflop range that is too weak, making the player exploitable by experienced opponents.

Influencing Factors

BTN AFq is influenced by several factors:

• Opponent tendencies: Players can profit by increasing AFq against opponents with high fold rates.
• Board texture: Dry flops (e.g., rainbow with no straight draws) generally correspond to higher AFq, as continuation bets are more likely to succeed.
• Range bias: If a player opens a very wide range from the Button preflop, their postflop AFq may naturally be lower, as many hands lack strong equity.

Notes

BTN AFq is a position-specific aggregated statistic. Its value is limited when the sample size is too small (e.g., fewer than several hundred hands). Additionally, it should be analyzed in conjunction with other metrics such as WTSD and W$SD to avoid misleading interpretations.
