A term used in poker, pot odds are defined as the ratio of the current size of the pot to the amount the player is currently considering adding to the pot.
For example, if there are 100 units already in the pot and the player is considering calling a raise of 10 units then the player is facing pot odds of 10 to 1.
The pot odds facing a player can help determine his next play. The lower the pot odds, the more likely it is that the player should fold.
