The aggression factor in poker

poker player with chipsIn 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.

Aggression measurement

If you are using a HUD (heads-up display), your aggression will be shown in numbers based on how aggressive you are. This is measured in frequency, not on the size of your bets.

The aggression frequency, 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.

Besides this, 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.

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 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. To win 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 have probably observed that you often 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 hand.

The important thing is to bet in every suitable spot, aggression can win the pot immediately or make the pot bigger (provided you have a strong hand).

The C-bet

One standard way of being aggressive in poker is to use the so-called C-bet (Continuous-bet). A C-bet mean 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, because after you have raised pre flop there will in general be few players left and often none will improve with the flop.

The exactly 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 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. 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.

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 again on the turn and was called again. Now, on the river the opponents checks to you the third time.

Many players avoid betting here because they are not sure on if they have the best hand, perhaps they are fearing a check-raise. 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. So, in these situations a small value bet will win you extra money that will contribute to your total winnings.

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 be whenever it is legitimate. That’s means, as long as you have value in your hand, including draws, or 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. Why:

  1. You can win the hand if the opponent fold.
  2. If you make a straight, you will probably be winning a bigger pot.
  3. 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.

As poker is a complex hand, aggression makes sense since it works on several levels.
