You are in a no-limit hold’em game and the first three cards (the flop) have been dealt. There is money in the pot, and your opponent puts in the remaining chips (all-in). You have nothing…except the flush draw. Do you follow or follow?
You cannot make a decision based on the information I provide. In order to make the right decision, you need to know how much money is in the pot, how much you need to pay to end the hand, and what your chances are of finishing the game.
Let’s assume that you win the hand if you make a flush; in this case, you need to stake 1.87 times the pot amount. If there is such an amount, it is correct to call.
This is because there are 9 cards to complete the flush (these are your out cards), and the last two cards are still open (the turn and the river). As shown in the table at the bottom of this page, you have a 35% chance of getting one of the 9 outs, or in other words, odds of 1.86 to 1. Therefore, you need a pot with odds greater than 1.86 which offers: 1.
This table shows you the odds and probability of completing the game, depending on the cards that suit you. Every player who wants to win at poker must become thoroughly familiar with this form.
How to Read Pot Odds and Paytables
In the left column under the heading OUTS is the number of cards, which will help complete our piece. Then, when the last two cards have not been dealt, and when only the fifth card remains, we get the odds and the probability percentage of ending the game in the two columns on the right.
Remember that the odds must be calculated card by card, and it is only correct to use the combined odds of the fourth and fifth cards when going all-in. This is because without going all-in, we may not be able to finish the game with the fourth card and would need to add more money to see the fifth card.
