All the cards are out. domino poker there’s £100 in the pot, your opponent bets £50 and with your hand, you’ll win half the time. Do you call?
Yes, the pot is now £150, that’s your reward. It’s £50 for you to call, that’s the risk. The Reward is 3 times the risk. The call is 33% of the pot. That’s the percentage of showdowns you have to win to break even. It’s simple to see that if you won 50% of the time, it would be a profitable call. I’d call every time.
In this example, all the cards are out so you don’t have to worry that your opponent is on a draw. In these situations pot odds combined with your own hand strength will give you an idea of whether to call or fold.
We can use pot odds when there are still cards to go as well. Suppose you have a nut flush draw on the flop and position. The pot is $30. First position leads out with a bet of $20. Two players call after him. The pot is now $90, its $20 for you to call. The call is 22% of the pot. You have a 17% chance of hitting your flush on the turn. Pot Odds say fold.
In this situation, when considering how strongly to re-raise, it is important to consider the size of the total pot in relation to the players stack sizes at the table. If you have aces and get a short stacked player to call into a pot roughly the same size as his stack and then check to him, he may push all in as a bluff, so you would be willing to let him see the flop to be able to stack him.
