When thinking about calling an opponents bet or raise, it is always interesting to know what your

equity is.

This is done by counting your outs, calculating your

odds and calculating your

pot odds.

If your odds are higher than your pot odds, it is a good idea to call, so in the long run you will be winning money.

Now, one issue with this, is that it takes some time to make all these calculations (even when you're using the rule of four).

To make it faster, I have made some calculations and an overview that I find easier to use.

The only thing you still have to do, is counting your outs and seeing how big the opponent's bet or raise is according to the pot.

In the table below, the first column is the number of outs you have

Second column is the bet or raise size made by your opponent on the flop (counting with still 2 cards to come).

Third column is the bet or raise size made by your opponent on the river (counting with still 1 card to come).

If the betsize made is smaller than the number in the second or third column, you can call.

Example 1:

You have 6 outs (two overcards) and the opponent bets on the flop 1$ in a pot of 2$. This means 0.5 times the pot.

Looking in the table next to 6 outs, it says 0.46.

0.5 is not lower than 0.46, so you should fold.

Example 2:

Same as above, but the pot is 3$

This means 0.33 times the pot.

0.33 is lower than 0.46, so you should call.

Example 3:

You have have 15 outs on the flop (OESD + flush draw).

It doesn't matter how much the opponent bets, you are ahead, so you can call everything.

Example 4:

You have 4 outs (gutshot) on the turn. The opponent bets 1 dollar in a pot of 10 dollar. You can call here, even though on the long term, this is a break even point.

Code:

21 all 5.31
20 all 3.34
19 all 2.37
18 all 1.79

16 all 1.14
15 all 0.93
14 all 0.77
13 12.65 0.65
12 4.5 0.54
11 2.51 0.45
10 1.58 0.38
9 1.16 0.32
8 0.85 0.26
7 0.62 0.21
6 0.46 0.17
5 0.34 0.13
4 0.24 0.1
3 0.16 0.07
2 0.1 0.04
