I've just started using poker tracker and think its really going to help my game, i've always put it off because i'm not very good at using these sort of things but i've found it easy to understand and use. The only thing i don't really get is the AF or Total Aggression Factor, what does it take into account? and is the number a percententage? Obviously the higher the number the more aggressive the player is, but i just wonder what stats it uses to get the number and what you can read into it.

I only ask because i realize that it is an important stat and i see it used in many a hand analysis', any explanation you guys could give would really be appreciated, thanks.

Thanks Mase. Ideally one will have two sets of AF values (pre & post flops). I can of course create a relative imagine of aggressive and passive players from this number.

However, Is there a suggested AF range that put players in passive, aggressive and excessively aggressive modes. e.g. AF=2, 6, 12 respt.

It's a funny stat because Aggression Factor actually is more a measure of passivity than it is of aggression. AF is calculated as :

(Total Bets) + (Total Raises) / (Total Calls) = AF

And is usually only used for Post Flop actions.

Since checks and folds don't register, a person can have a very high AF but not be a very aggressive player. They could simply be checking and folding a lot and rarely calling. By looking at only the AF, you'll often be mislead as to a persons actual aggression level. That doesn't stop it from being a useful stat though, and it becomes even more useful when used in conjunction with the Aggression Frequency stat.

Hi dsvw56,

Your formula is actually wrong

It's a funny stat because Aggression Factor actually is more a measure of passivity than it is of aggression. AF is calculated as :

(Total Bets) + (Total Raises) / (Total Calls) = AF

It should be:

((Total Bets) + (Total Raises)) / (Total Calls) = AF

AF is common but for aforementioned reasons, it's not an entirely accurate measure of aggression. AF of less than 2 indicates a very passive player who should be very easy to exploit. Solid players are usually in the 3-4 range, and really tough aggro players can run higher. Of course you need a decent sample size for these to be entirely meaningful -- over a few dozen hands it's not uncommon to see double-digits here when even non-aggressive players run good.

Aggression Frequency (AFq or AF%) is becoming a more popular measure. It's calculated as (raises+bets) / (raises+bets+calls+folds), which takes more passive action (+folds) into account. Checks aren't counted but really don't need to be, because unless hands go check-check all the way to showdown -- and most won't -- some other aggressive or passive action must follow a check and will thus be represented. Good aggressive players will typically have AFq's of around 25-40%, give or take.

Both are postflop aggression stats. Preflop aggression is determined from other stats, namely PFR in relation to VPIP, along with 3+bet tendencies. Some are promoting RFI (Raise First In) as a replacement for PFR, since recent changes to both PT and HM PFR stats ignore hands entirely where you don't have a chance to PFR, and thus can skew the numbers. Especially over smaller sample sizes.
