The aggression factor in poker
In poker, aggression is beneficial in many situations. An aggressive player will often perform better than a passive in the long run. This article explains why.
If you are using a HUD (heads-up display), your aggression factor will be shown in numbers based on your bet and raise action. This is measured in frequency, not on the size of your bets.
The aggression factor, abbreviated AF, is calculated: (bets + raises) / calls.
For example, if you have done 10 bets, 5 raises and 7 calls your AFq is 2.1.
Folds are not counted in AF, but there is also aggression frequency, abbreviated AFq. The number it represents is calculated: (bets + raises) / (bets + raises + calls + folds) * 100.
For example, if you have done 10 bets, 5 raises, 7 calls and 15 folds your AFq is 40.5.
So, a tight-aggressive player has generally a high AF, but a moderate AFq. A loose-aggressive player on the other hands tends to have AF and AFq that are both high.
Calculated aggression and how it’s done
Aggression is not an end in itself, it’s a mean for finding an optimal exploiting route in the game. Likewise, aggression is not meant to be used in all situations, but when aggression is called for it’s a lost opportunity to not use it.
Aggression wins small and big pots. The small pots are often won by the simple fact that a player bet and the rest is folding. Winning many small pots will in the long run be important for the result.
Aggression wins also big pots and this can be seen in some more complex ways. By being aggressive, your table image will change. Other players will probably observe that you routinely bet and raise, therefore, they will not be sure that you have a great hand when you finally get one. That means you will get more callers and by that winning bigger pots with your great hands.
The important thing is to bet in every suitable spot, aggression can win the pot immediately or (provided you have a strong hand) make the pot bigger.
Methods for aggression 1: The C-bet
One standard way of being aggressive in poker is to use the so-called C-bet (Continuous-bet). A C-bet means that after you have raised pre flop you follow up by raising again directly after the flop. The concept is to raise consequently in a high frequency and also when you don’t hit the flop. By doing this you will simple win many hands, by raising pre flop you will thin out the field and among the rest none will in most cases improve with the flop.
The exact frequency you will use for your C-bet can be as high as 90%. In other words, you raise after the flop 9 out of 10 times if you have been raising pre flop (the situation changes however, if someone is 3-betting you). Some players C-bet 100%, but this is not optimal since they became predictable. A 90% C-bet frequency is also pretty much and it you prefer 80% that can perhaps be as good – it all depends on how the opponents adjust.
Methods for aggression 2: The value bet
Some players get cautious on the river and only check after their opponent have checked. For example, you hold A-J and the board is A-5-7-2-3. You play heads-up and your bet was called after the flop, you bet on the turn and it was called again. Now, on the river the opponents checks to you the third time.
Many players avoids betting here because they are not sure they have the best hand, perhaps they are fearing a check-raise as well. The thing is, in most cases they will not be check-raised since this is relative unusual and most often their opponent has a weaker ace or a weaker pair.
Yes, sometimes your opponent may check-raise and you may have to fold, but in the majority of cases you will get another call by weaker hand. In these cases, a small value bet will win you extra money that will contribute to your total winnings.
Methods for aggression 3: Bluff with missed draws
Instead for being annoyed after another missed draw, you should often take a bluff into consideration. There are logic reasons to bluff with your missed draws.
Let’s assume the pot is 1200, if you bet 600 on the river after you missed your flush draw you have only to succeed 1 out of 3 to go even. If you check with nothing you will almost definitely lose the 1200 pot.
The math behind this
The pot 1200 + your bet 600 = 1800
When you win + 1200
When you lose – 600
As Mike Caro used to say: “You have nothing invested in the pot – ever.”
Bet as often as you can when it’s legitimate

The C-bet and the value bet are two important concepts and ingredients in an aggressive poker style. In general, you should bet be whenever it's legitimate. That means, as long as you have value in your hand, including draws, or as long as you have fold equity, you should often choose to bet/raise.
For example, raising with an open straight draw can be a strong play. Here's why:
- You can win the hand if the opponent fold.
- If you make a straight, you will probably be winning a bigger pot.
- You make it harder for the opponent to read your hand, he will often guess that you have a pair, two pair or three of the kind.
Since poker is a complex game, aggression makes sense because it works on several levels.
