Aggression

[SaynotoKlaus]

How does HM determine aggression , and whats the difference between the two types of aggression?
I red that guide where stats are explained but i still didn't understood . If a dude has high agg factor what does it mean , that he bets often or that he make large bets?
I have this guy in my database , who has inf agg factor on all streets , i played 80 hands at the same table with him. Is he some sort of maniac or what?

Aggression Factor = (Bets + Raises) / Calls
(checking/folding doesn't affect it)

This results in a value between 0 and INF (infinite)
If a player never calls, but always bets/raises, his AGG will be infinite.

Both Aggression Factor and Aggression Percentage are mostly used in postflop decision making. Since it will tell you the likelihood the opponent will bet on each street.


Aggression Percentage = aggressive action on each street. So if I bet the turn and the river but check the flop I would have 66% Agg Pct because I made 2 out of 3 aggressive actions.

So it's ( (Bets + Raises) / (Bets + Raises) + Calls ) * 100%.

In the example above the action results in a Agg Pct of 66%.
The Agg Factor would be: 2 / 1 = 2
Both results mean the same: the opponent is 2x more likely to bet, than he is to call.
So if you have a GOOD hand on the turn/river, and you're out of position, just check to this opponent hoping he will bet.

Calling doesn't affect Aggression Percentage , right?

[Patvs]

Folding/Checking doesn't affect it.

Aggression Factor = (Bets + Raises) / Calls


Aggression Percentage = ( (Bets + Raises) / (Bets + Raises) + Calls ) * 100%.

Calling (see formulas) does.

Hmmm... What we have done on pre-flop in this case? Why our pre-flop action doesn't affect calculations?

[Patvs]

Your preflop actions will also be used for the aggression stat.



Edit: it's based on postflop! play only

[SamMan]

Your preflop actions will also be used for the aggression stat.

Suppose you are mistake, since as I discover after my previous post formula to calculate AggPct is:

Evaluate="(BetOnFlop+BetOnTurn+BetOnRiver)*100.0/(SawFlop+SawTurn+SawRiver)"

No pre-flop as you see...

[Patvs]

Ah you're right. It's postflop only.

Bump. Can someone clarify this? In the example, you have a flop check affecting the Aggression %, but then in your formula you have no mention of checks (or folds). Can you clearly state whether checks and folds are calculated into Ag%?

( (Bets + Raises) / (Bets + Raises) + Calls ) * 100% <-- no checks or folds

(Bets + Raises ) / (Bets + Raises + Calls + Checks + Folds) * 100 <-- uses checks and folds

or to put more simply if it does use checks and folds: (Bets + Raises) / Total # of Actions * 100.



Example using (Bets + Raises) / Total # of Actions * 100:

Flop:
1A) A Bets - 1 Aggressive - 100%
1B) B Calls - 1 Passive - 0%

Turn:
2A) A Bets - 2 Aggressive - 100%
2B) B Raises - 1 Aggressive 1 Passive - 50%
3A) A Calls - 2 Aggressive 1 Passive - 67%

River:
4A) A Checks - 2 Aggressive 2 Passive - 50%
3B) B Bets - 2 Aggressive 1 Passive - 67%
5A) A Raises - 3 Aggressive 2 Passive - 60%
4B) B Folds - 2 Aggressive 2 Passive - 50%

Resulting in:
Player A having 60% Ag% (3/5) Total.
Player B having 50% Ag% (2/4) Total.

Removing the check and the fold from the calculation would result in:
Player A having 75% (3/4) Total.
Player B having 67% (2/3) Total.
