A separate pot created to deal with the situation of one player going “all in”, while other players still have money remaining that may be bet.
Here is an example of a side pot:
Three players are involved in a hand. Players A and B each have $200 and player C has $100. If player C goes all in and is called by both other players, the pot will be $300, which is the maximum amount that player C can win. If the other two players decide to bet their remaining $100, a new pot containing only $200 will be created. The side pot of $200 can be won only by players A or B. It is possible to win a “side pot”, while still losing the original or “main” pot.
