AFq from MP

Overview

AFq (Aggression Frequency) is a poker statistic that measures how often a player takes an aggressive action (bet or raise) when they have the opportunity to do so. It is distinct from Aggression Factor (AF), which is the ratio of aggressive actions to passive ones. AFq is expressed as a percentage. 'From MP' specifies that the statistic is filtered to only include hands where the player was in Middle Position (MP).

Middle Position in Poker

In a full-ring game (9 or 10 players), Middle Position typically refers to seats 4-6 (UTG, UTG+1, MP, MP1, MP2 depending on exact naming). In 6-max, MP is often the cutoff or the seat after UTG. The exact definition can vary by poker room, but generally MP comes after early position and before late position.

Importance of AFq from MP

Filtering AFq by position helps understand a player's positional tendencies. A high AFq from MP indicates a player who frequently opens or raises from middle position, suggesting a wide range or aggressive style. A low AFq suggests a more passive approach, often indicating a player who prefers to limp or call, or only raises with strong hands from that position.

Since MP is not as strong as late position (CO, BTN) nor as vulnerable as early position (UTG), the optimal AFq from MP is usually moderate. Players with very high AFq from MP may be exploiting too many marginal hands, while very low AFq may indicate a predictable and exploitable style.

Theoretical Considerations

In GTO (Game Theory Optimal) strategies, aggression frequencies vary by position. From MP, the recommended opening ranges are tighter than from the button but wider than from UTG. Therefore, a GTO player's AFq from MP would be moderately high, typically around 50-70% for the hands they choose to play. However, AFq applies only to hands that reach a decision point (i.e., when there is an opportunity to be aggressive). Passive players may have AFq below 30%, while aggressive players might exceed 80%.

Usage in Hand Analysis

When reviewing a player's stats, AFq from MP can reveal leaks. For example, if a player has a high VPIP (Voluntarily Put Money In Pot) from MP but low AFq, they may be calling too often, not raising enough premium hands, or failing to c-bet. Conversely, a low VPIP but high AFq could indicate a tight but aggressive player who only enters pots with a raise.

Limitations

AFq does not account for the size of aggressive actions (e.g., min-raise vs. large bet). It also requires a sufficient sample size to be reliable. For MP, the number of hands observed may be smaller than overall AFq, so variance can be higher.

Conclusion

AFq from MP is a nuanced statistic that provides insight into a player's aggressiveness from middle position. It is best used in conjunction with other positional stats (e.g., PFR, VPIP, AF) and population tendencies to form a complete picture of a player's strategy.
