关煞位攻击频率（CO AFq）

Definition

CO AFq refers to the frequency with which a player in the Cutoff (CO) position takes aggressive actions (i.e., bet or raise) after the flop (flop, turn, river), typically expressed as a percentage. This statistic comes from poker tracking software (e.g., Hold'em Manager or PokerTracker) and is used to evaluate a player's post-flop aggression from the CO position.

Calculation

AFq = (Number of Bets + Number of Raises) / (Number of Bets + Number of Raises + Number of Calls + Number of Folds) × 100%. Note: AFq only counts rounds where the player actually faces a decision; it does not include checks or automatic checks from the blinds.

Usage and Interpretation

• High AFq (>55%): The player is extremely aggressive post-flop from the CO position, frequently betting or raising, often indicating strong hands or continuous pressure.
• Low AFq (<40%): The player tends toward passive play, calling or folding more often, and may rely more on showdown value.
• Medium AFq (40-55%): Typical aggressive player, balancing value bets with bluffs. Since the CO position is before the button, it offers positional advantage but less than the button. Therefore, a player's AFq in the CO is usually slightly lower than on the button but higher than in middle position.

Notes

• AFq should be considered alongside preflop raise percentage (PFR) and total number of hands; it may be unreliable with a small sample size.
• Different table dynamics (e.g., opponent types, stack depth) can affect the interpretation of AFq.
• Professional players may deliberately adjust their AFq to balance ranges and avoid being exploited.
