How to Size Your Three-Bets Properly

Ronny Johanson

In today's LAG and TAG-dominated online short-handed games, three-betting is as common as non sequitur flashbacks on The Family Guy.

There are two reasons to three-bet:

1) for value, i.e. you have a good hand (AA, KK etc.) and would like to get value from worse hands, or

2) as a bluff/semi-bluff - in which case it's known as a light three-bet.

When you three-bet light, you're making a semi-bluff at the pot. You know that your opponent is raising light, you can three-bet him light and have him fold, winning you the pot immediately.

This leads to you winning more pots without showdown as well as getting action on your real, three-bet-for-value-type hands.

But although the practice of three-betting light is commonplace these days, many players still routinely size their three-bets incorrectly.

Some players size their reraises on the strength of their own hand.

They bet a bigger amount when they have a weak hand and want their opponent to fold and bet less when they are betting for value.

This is incorrect thinking. A skilled opponent will pick up on this and exploit you.

Your bet sizing should not be determined by the strength of your hand.

Position is key.

Position Dictates Everything

So if hand strength isn't the deciding factor, what is?

The answer is position. You hear it over and over again - position dictates everything in poker.

For determining the size of your three-bet it's no different. When you're in position you can get away with a smaller three-bet size.

This is because you will be last to act for the entirety of the hand. Since acting last is such a huge advantage, you can punish the out-of-position player often, regardless of your hand strength.

When you are in position a good reraise size would be around 3x to 3.5x the original raise.

It's big enough that your opponent does not have an automatic call, yet it doesn't risk an unnecessary amount of chips.

Let's look at an example.

Six-max $1/$2 No-Limit game; effective stacks $200. You're on the button with A Q. Action is folded to the cut-off, who makes it $6.

You reraise to $18. Your opponent calls and you see a flop of J T 3. Your opponent checks and you bet $24. He folds.

Since you're in position, you gain information with him acting before you.

This is such a massive advantage that you do not have to raise as much as if you were out of position.

Upping Your Bets Out of Position

When you're out of position, life is always tough. Your decisions need to be made without the advantage of knowing your opponent's action.

Since he always has the last say, he's in control and you're at a disadvantage.

To make up for this you always want to reraise more from out of position.

Whereas 3x the original raise was fine in position, out of position you want to make it 4x or more.

You essentially would like to charge him for the privilege of playing in position against you.

When you're in position, you don't mind seeing a flop and letting your edge manifest itself. When you're out of position, you want to discourage him from calling as you will often be left guessing post-flop.

Giving your opponent good odds and position is a mistake, so let them know you mean business with larger out-of-position raises. The larger raise helps negate your positional disadvantage.

Another example:

Six-max $1/$2 No-Limit game; effective stacks $200. You have Q Q in the big blind. Action is folded to the button, who makes it $6. You make it $26.

The $26 bet is going to get the job done a lot more effectively than the $18 bet is. You want to minimize your time playing out of position, so with the bigger reraise you're saying, "Fine, if you want to play this pot in position, you're going to have to pay."

Add it up: 1x for every caller.

Rules of Thumb for Multiway Pots

If you're reraising a raise and a call, you have to make your reraises even larger. That's because your reraise will have to make it through two players instead of just one.

You don't want to size your bet so that the original raiser calls and then the other caller overcalls. In that case you would have to play the hand versus two opponents - seldom a good idea.

When you're in position versus a raise and a call, you should add 1x the original raise for every caller in the pot. So if one player calls the first raise, go 4x; if two, then 5x; etc.

If you're out of position and against multiple players add 1x for every caller and then at least another 1-2x the original raise for being out of position.


In today's games you're going to be three-betting fairly frequently.

If you routinely make mistakes with your three-bet bet sizing, you're ultimately making it more difficult to win.

Keep your three-bets sized properly to your position and to the number of players left in the hand, and you will make it easier on yourself in the long run.
