Bet Sizing

If you decide to bet, it is very important to wager the right amount.

Although fashions in bet sizing are always changing, and advanced players have different reasons for betting different sizes, the following are widely accepted definitions:

  • Small bet: about half the pot.
  • Medium sized bet: between half and three quarters of the pot.
  • Large bet: more than three quarters of the pot.

This applies in cash games or tournaments. In the former, the pot will be real money, while in the latter it will comprise tournament chips. But the general guidelines apply in both instances.

Small Bets

The size you want to bet will always depend on the specific situation, but typically players might want to make small bets on a dry board (ie, where there are few connecting cards), on the river (when all community cards have been exposed) or as a continuation bet (ie, following up a pre-flop raise).

On a dry board – If there are few to no draws possible – for example a flop of  K73 – then it is not possible to have a flush draw or an open-ended straight draw. Therefore it is not as important to protect a big hand because the chances of it being outdrawn are slim. Therefore it is OK to bet relatively little, in the hope of attracting a call to swell the pot. (Remember, if you typically bet small with a good hand then you should typically bluff small as well. Good opponents can spot changes in patterns and can figure out when you are bluffing and when you are not.)

On the river – If all the community cards are out already, no one can outdraw your hand. It follows that it is no longer necessary to protect a big hand. Therefore the situation is similar to an extremely dry board and bets on the river tend to be smaller than bets on other streets.


A continuation bet means to bet on the flop after raising pre-flop. You are continuing your aggression, hence the name. This is a way to pick up the pot if your opponent missed the flop. It’s not necessary to make a big bet in order to do so as your opponent should already be convinced of the strength of your hand from your pre-flop aggression.

Big Bets

In certain situations, big bets can be a very strong weapon. They will put a lot of pressure on your opponents and force them into decisions that can cost a lot of their chips. Big bets can be useful to bluff people off decent hands, gain huge value with strong hands or to protect against strong draws.

Here are typical situations when to make a big bet:

On a draw heavy board – In contrast to a “dry board” described above, you should bet big when there are many ways in which your strong hand can be outdrawn. Suppose you are holding 105 in the big blind. Several players call and nobody raises, so you see a flop for free. It comes 1085 and you have two pair.

You hand is strong at this stage, but a lot of cards are dangerous. Your opponents could easily make a flush, a straight or a better two pair on the turn or river. You should make a big bet here, possibly even bigger than the size of the pot.

Two pair is a hand that often calls for big bets because although it is strong enough to be ahead most of the time, it is weak enough that it can be outdrawn on turn and river. (This only holds true if there is no pair on the board. Otherwise a lot of players might have two pair and your hand is usually not strong enough to make a huge bet.)

Pre-flop – Before any community cards have been dealt, even a very strong hand can be vulnerable against a significantly weaker one. Even if you hold AK and your opponent holds 62 you are less than a two to one favorite. If you raise pre-flop it should almost certainly be a large raise to force out holdings that might beat you.

With the nuts – If you are lucky enough to have the best possible hand, you might want to bet big in order to build a gigantic pot. (Sometimes you also want to pretend to have the nuts and make a huge bluff.)

Medium Bets

If you have decided that a bet is necessary, but the situation isn’t listed above, then a medium-sized bet is probably in order.

Bet Sizing Examples

  • A decent pocket pair pre-flop. You are JJ holding in the cut off seat. Two players in front of you call. It is important to make a big raise, up to five or six big blinds here. You are pretty confident to hold the best hand and you want an opponent to pay dearly if they want to out-flop you.
  • Protecting your hand on the flop. In the same scenario as above, both limpers call after you raise to five big blinds. The flop is 1063. The board is pretty dry but your hand is vulnerable to over-cards, and you could be outdrawn if an ace, king or queen comes on the turn or river. You should definitely protect your hand by betting. A medium sized bet will do the job
  • A monster on the river. You are holding K10 and the board is QJ46A. You have the nuts. You have one opponent, who checked to you. It is OK to bet big here. Maybe he caught an ace on the river and wants to see the showdown.
  • A decent hand on the river. On the same board as above and with the same opponent, but this time you have A6. You were trying to hit a flush after the flop but made two pair on turn and river instead. When he checks to you, you should make a small bet. If he has a queen or a jack, for example, or even a hand like A9, he might call you to see if you have a busted flush draw.
  • A marginal hand on the river. Consider the same board again. This time you are holding KJ for third pair. This is a hand you should just check behind. Remember that you always need a purpose to bet. You shouldn’t go for a value bet here because your hand is not strong enough for that. It’s obviously not necessary to protect your hand from draws because all cards are out already. Bluffing is not necessary either because if you opponent has a weak hand, you will win the showdown anyway. And there is no need to bet for information either. If you check, the cards will get turned over, which will give you all the information you need.
  • A terrible hand on the river. Yet again the same board with your lone opponent. Unfortunately you are holding 98. You had a nice draw but it missed (a “busted” draw) and now you have nothing more than nine high. This is a good spot for a bluff. Usually you should bet small and represent an ace. Once in a while it’s OK to make a big bluff, representing a straight.
