You also have to decide on whether the hand that you are trying to hit will win you the pot or not.
How to calculate pot odds:
In this example, if the current pot contains $80, and the amount required at the next call is $20, the pot is laying you odds of $80 to $20 or 4 to 1.
As long as your odds of making the best hand are 4 to 1 or better than making the call is the right move. A hand that is 4 to 1 means that you will hit once in every 5 tries. You will hit the draw 20 percent of the time.
This next example takes into account calculating pot odds and outs.
Assume that your hole cards are a six and a seven (for this example suits do not matter) and the flop came down 8-9-3.
In order to complete your hand you need a 5 or 10. You have eight outs – 4-5’s and 4-10’s. Multiply your outs (8) by 4 and you get 32. You have a 32 percent chance of making your hand. If there was only one card left to draw you would multiply by two.
A 32 percent chance of making your hand means you have a 68 percent chance of NOT making your hand. This is roughly 2 to 1 that you won’t make the hand. So, as long as the pot contains $2 for every $1 that you have to call, it is worth going after your straight.
Doing these quick calculations and interpreting them can be very difficult and confusing for a beginner (and many advanced players as well!). But I would recommend that you at least be able to quickly calculate your outs to give you an idea of just how likely you are to make your hand.
