The game of poker is based on the theory of probability, so every beginner has to master the fundamentals of the poker math. Having learnt to count pot odds in poker, you can take the right and mathematically correct decisions in the struggle for the pot.
Thus, you will know whether you should call opponents’ bets to improve your hand or you should better fold.
How to calculate Pot Odds
It is actually very simple to calculate pot odds and even a schoolboy can do it. So, playing in the poker room, you’ll have plenty of time to calculate your odds and outs of winning.
Pot odds are the ratio of the chips (money) in the pot to the size of the bet you should call.
For example. There are 9 $ in the pot and your opponent bets 1 $. So you have to place 1 $. Thus, the odds will be 10:1 – because in the pot there are 10 $ (9 $ plus 1 $ of your opponent), but you have to place 1 $.
Knowing the pot odds, we compare them with the chances of winning (see chart below). If the pot odds are higher than the odds of winning, we call, if lower – we fold.
On the flop, you have a straight draw. In the pot there are 18 $ and your opponent bets 3 $. So, your pot odds are 7: 1 (21:3). 18 $ + 3 $ = 21 $ is a total bank, 3 $ is a bet you have to call. With incomplete straight draw you have 8 outs, what under the chart is 5: 1 (the exact value is 4.9 to 1). As we can see, the pot odds (7: 1) are higher than the odds of winning – accordingly we call.
On the flop, you have a flush draw, and there are 12 $ in the pot. Your opponent bets $ 5. So, the pot odds will be about 3:1 – (12 $ + 5 $) / 5 $. Odds of winning are 4: 1. Therefore, in this case the best solution will be fold, since the pot odds are less than the chances that you will collect flash.
Suppose on the flop you have straight draw and flush draw, and in the pot there are 280 $. Your opponent bets 100 $. So, in the pot there are 380 $ and you have to place 100 $ to open one card. In this case, the pot odds are 3.8:1, and your chances of collecting straight or flush are 2.1:1. So, mathematically correct decision is to call.
Of course, it does not mean that you will always get the right cards, and you will win, but with a large number of hands played, you will benefit.
If there is no odds chart at hand, you can calculate them yourself. To do this, divide the number of cards left in the deck, minus your outs, by the number of outs. For example, you have a straight draw, so you have 8 outs. In the deck there are 47 cards, of which 8 are your outs. So, (47-8) / 8 = 4.85, round it off and get 4.9, that can be seen in the odds chart.
If you do not want to count yourself, you can use poker calculator. It makes all the necessary calculations online at the table of the poker room.
How to use this chart:
- Number of outs is the number of cards needed to improve the hand.
- 1 card on the turn is the likelihood that on the turn you will get the needed for the victory card.
- 1 card on the river is the likelihood that on the river you will get the needed for the victory card.
- 2 cards (on the turn or river) is the likelihood that on the turn or river you will get the needed for the victory card.
Also note that if on the flop you called the opponent’s bet, and the pot odds were higher than the chances of winning, but on the turn you did not get the correct card, you have to recalculate your chances in accordance with the size of the pot and your opponent’s bet.
