按钮位进攻频率（AFq from BTN）

Overview

AFq (Aggression Frequency) is a metric that measures how often a player takes aggressive actions (bet or raise) rather than checking or calling in a given situation. "AFq from BTN" specifically refers to the frequency with which a player on the button (BTN) chooses to bet or raise when facing the flop, turn, or river. This metric is typically used to assess a player's aggressiveness when in position (the button).

Calculation

AFq = (Number of bets + Number of raises) / (Number of bets + Number of raises + Number of checks + Number of calls) × 100%. For example, if a player on the button makes 100 decisions total, betting 30 times, raising 10 times, checking 40 times, and calling 20 times, then AFq = (30+10)/(30+10+40+20) = 40/100 = 40%.

Meaning and Application

• High AFq (e.g., >50%) indicates the player tends to be aggressive on the button, possibly holding strong hands or frequently bluffing using position.
• Low AFq (e.g., <30%) indicates the player is more passive, preferring to check or call, and may lack bluffs or value bets.
• Unlike AF (Aggression Factor), AFq does not distinguish the ratio of bets to raises but directly reflects the proportion of aggressive decisions.
• On the button, a high AFq is usually advantageous because position allows controlling the pot and acting last. However, excessive aggression can be exploitable.
• Opponents can adjust their defensive strategies based on this data: against high AFq players, increase bluff-catching or raise back; against low AFq players, value bet more frequently.

Notes

AFq is affected by sample size and can be volatile in small samples. It is recommended to rely on this metric only after more than 100 decisions on the button. Additionally, this metric does not account for board texture, player style, or other dynamic factors, so it should be combined with other statistics (e.g., VPIP, PFR) for a comprehensive analysis.
