Pot odds represent the ratio between the size of the total pot and the size of the bet facing you. Keep in mind that the size of the total pot includes the bet(s) made in the current round. For example, if there is $2 in the pot and your opponent bets $1, your pot. Pot odds are defined as the ratio between the size of the pot and the bet facing you. For example, if there is $4 in the pot and your opponent bets $1, you are being asked to pay one-fifth of the pot in order to have a chance of winning it. A call of $1 to win $5 represents pot odds of 5:1.
