Middle Position Aggression Frequency (AFq from MP)

Concept

[AFq] (Aggression Frequency) is a metric that measures a player’s aggression in a specific position or overall. It is calculated as: (Number of Bets + Number of Raises) / (Number of Bets + Number of Raises + Number of Calls). This metric excludes folds and checks, reflecting only a player’s aggressive tendency when actively involved in the pot.

Significance from MP

The Middle Position (MP) is an early-to-middle position in Texas Hold’em, typically referring to UTG+1 in a 6‑handed game or UTG+1 and UTG+2 in a 9‑handed game. Players in MP must face potential counter‑attacks from subsequent positions (CO, Button, Blinds). Thus, AFq from MP reveals a player’s aggressiveness when out of position. A high AFq (e.g., >2.0) indicates a tendency to c‑bet with strong hands or semi‑bluffs, while a low AFq (e.g., <1.0) suggests a preference for passive calling or showdown.

Strategic Applications

• Opponent Reading: If an opponent has a high AFq from MP, expect frequent flop c‑bets. Consider raising with made hands or delayed bluffs. If AFq is low, the opponent may fold marginal holdings easily—apply pressure with persistent c‑bets.
• Self‑Adjustment: In MP, adjust your AFq based on hand range. For example, a linear range may justify a higher AFq, while a polarised range may produce mixed values. Generally, because MP faces many players yet to act, maintain a balanced AFq to avoid exploitation by re‑raises.

Notes

AFq does not indicate the specific nature of actions (e.g., value bets vs. bluffs). Combine it with other metrics such as [WTSD] and [WWSF] for a fuller picture. Also be aware of sample size—AFq can fluctuate widely in a single session; usually several hundred hands are needed for statistical significance.
