Ja više ne kužim kako interpretirati AF ili AFQ.
Aggression Factor:
(# of bets + # of raises) / (# of calls)
Aggression Frequency:
(# of bets + # of raises) / (# of bets + # of raises + # of calls + # of folds)
Sa P2P of AF-u (sry puki, nadam se da se ne ljutiš šta spamam temu
)
AF – Agression Factor is the 3rd of the typical PT stat trinity. Almost everyone uses AF (along w/ VPIP and PFR) to describe players, yet AF is probably the most misunderstood and misapplied commonly used Poker Tracker stat. So what is AF? As I mentioned above, AF = (bet% + raise%)/call%, but what does this really give us? Well the resulting number gives us a way to analyze how aggressive a certain player is. By looking at the formula, it is plain to see that betting ang raising increases our AF, while calling lowers it. Seems pretty simple right? Wrong! AF, can not be viewed in a vacuum as it relies heavily on other factors such as VPIP, Fold Flop% and WTSD% and is very relative to a player’s “style”. Let’s look at some examples:
We have 2 players at our table which have the following stats over the same amount of hands (let’s basically ignore convergance issues, and assume the sample in converged):
Player A : 13/10.5/2.5 (VPIP/PFR/AF)
Player B : 75/9/1
Now if we just looked at AF alone, one would think that Player A is more aggressive since his/her AF is 3. But is that really the case? Player A has a VPIP of 15 which basically is a range of 77+,A8s+,K9s+,QTs+,JTs,ATo+,KJo+. Note that I do understand that there is a difference between what a 13 VPIP player is playing and just the raw top 13% of hands. I do not want to adjust the range due to player tendancies, but thankfully it is not needed for this execise. Player A has a very small range compared to Player B, who at a VPIP of 75%, sits with a range of 22+,A2s+,K2s+,Q2s+,J2s+,T2s+,92s+,83s+,73s+,63s+,5 2s+,43s,A2o+,K2o+,Q2o+,J4o+,T6o+,96o+,86o+,75o+,65 o. Player A also has an AF 2.5 times that of Player B. Is he really 2.5 times as aggressive? Well the answer is MAYBE, BUT PROBABLY NOT! I can already hear your thoughts, “Wait… maybe?”. If Player B was as fit/fold as he is loose, then he will be folding a ton of his range on the flop. If he folds his additional 60% of played hands, plus he folds just as often as Player B does with his top 15%, then yes, Player B would be 3 times as aggressive. The reason I say probably not is because you will hardly ever find a player that plays so loose PF (75 VPIP), yet folds so very much on the flop.
Player A is almost always going to be the aggressor heading into the flop because he plays so few hands, but most of the hands he does play, he is playing strong PF with a raise. It’s pretty easy see that having such a small range of hands (all very strong/premium) will result in someone betting or raising 2.5 times as much as they call. Having such a strong range, this player will also not have to rely on a good flop to continue betting and raising. Compare that thought process to Player B now. Player B must be very aggressive if he is betting and raising at the same clip as he is calling. He is going to be betting and raising very often (equally often as calling if AF = 1) which will be extremely difficult with such a wide range of hands unless of course he is folding a ton of the flop as I mentioned earlier. The above example shows how AF is relative to playing styles in relation to VPIP and Fold Flop %. WTSD% is another stat which can have a pretty significant impact on a player’s AF. Obviously, the more a player makes it to SD, the more opportunities the player will have to bet/raise/call/fold. Players with high WTSD numbers have to work harder (be more aggressive?) to keep their AF from dropping. These types of players will be very good at value betting, or very bluffy, or just stubborn (bet/raise several barrels throughout entire hands).
A typical TAG player will have an AF between 1.5 and 2.5. 6max players should be very careful not to spew by being over aggressive just because it is shorthanded, while FR players must contend with seeing flops with potentially more people. FR players will be playing less hands and raising less PF than if they were playing 6max, thus actually making it easier to keep their AF up. Since we typically do not consider preflop when discussing AF, FR and 6max AFs will be fairly similar.
AF convergence is another interesting topic. One could assume that because there a many decision possibilities in each individual hand, that AF would converge faster than VPIP or PFR. The problem here is that the “type” of hand can have a huge impact on AF of smaller sample sizes of hands. Imagine a player flops a set and gets to raise/cap the flop, bet/3bet the turn and bet the river. This player has had 5 actions and bet them all. If this player is tight and aggressive, it will take a while for his AF to normalize. The more aggressive the player, the longer it will take for his AF to become something truly comprehendable, while a very passive player will typically show a quicker stabilization.
Are there other ways to measure a player’s aggression? I’m sure there are, but I’m not gonna address any approaches here, though it would be a great topic to cover, even if only in a thread for exploratory ideas. I would contend that any method should take folds and WTSD% into consideration.
So in conclusion, not all similar AFs are ACTUALLY similar and not all sub-1.25 AFs = passive.
