CO位激进系数（CO AF）

Overview

CO AF is a statistic in poker data analysis, referring to the Aggression Factor of a player in the Cut-off position (CO, the first position to the left of the button). AF is typically calculated as (bets + raises) / calls, reflecting a player's tendency to be aggressive or passive in a hand.

Interpretation and Significance

• CO Position Characteristics: CO is the last non-blind position to act pre-flop, offering positional advantage and being a common spot for stealing blinds. Therefore, CO players often have a higher AF than early position players.
• Value Meaning: A higher AF indicates the player prefers to bet or raise proactively; a lower AF (e.g., below 1) suggests the player calls more often and plays passively.
• Strategic Application: Analyzing an opponent's CO AF can help gauge their post-flop aggression. For example, an opponent with a high AF may frequently continuation bet from CO or bluff with weak hands; a low AF opponent may only bet with strong hands, making them easier to read.

Notes

• Using AF alone may introduce sample bias; it is recommended to evaluate it in conjunction with hand count (sample size), VPIP, PFR, and other metrics.
• The reference baseline for AF can vary depending on the game type (cash games vs. tournaments) or table dynamics.
