AFq from UTG
AFq from UTG
UTG Position Attack Frequency AFq from UTG Measures the frequency with which a player actively bets or raises from UTG under the gun position, i.e., the proportion of aggressive actions among all non-check actions.
Overview
AFq (Aggression Frequency) is a metric that quantifies a player's level of aggression in a given situation. When the specified position is UTG (Under the Gun, the first to act preflop), this indicator reflects the player's behavioral tendencies after entering the pot from UTG.
Calculation
The formula for AFq is:
AFq = (Number of Bets + Number of Raises) / (Number of Bets + Number of Raises + Number of Calls + Number of Folds)
Note that checks and showdowns are typically not included in the denominator. AFq ranges from 0 to 1, with higher values indicating a player is more inclined toward aggressive actions (betting or raising) rather than passive calling or folding.
Example
Suppose a player faces 100 non-check decisions from UTG (i.e., must choose bet, raise, call, or fold), including 30 bets, 10 raises, 20 calls, and 40 folds. Their AFq = (30+10) / (30+10+20+40) = 40/100 = 0.4, or a 40% aggression frequency.
Application and Interpretation
From UTG, due to the positional disadvantage preflop (acting first), the opening range is typically tight. Therefore, a desirable AFq from UTG is usually high, indicating that the player continues to be aggressive after entering the pot and avoids passive play. A low AFq may suggest that the player often calls or folds after entering the pot from UTG, making them vulnerable to exploitation.
This metric is often analyzed alongside VPIP (Voluntarily Put Money In Pot) and PFR (Preflop Raise). For example, if VPIP from UTG is low but AFq is high, it shows the player only plays strong hands from that position and extracts value aggressively.
