Texas hold 'em
If a player goes All In and two or more players are still betting, the other betters can raise each other until they both call (or one of them also goes All In). A "side pot" is made in this case. It is the difference between the final bet and the first person's All In. Only the two players were not All In can win this pot. If the All In player wins the hand, he wins the main pot (his money plus an equal amount from each other player) and which ever of the other two players had the better hand wins the side pot. In an eight player game, it is possible to have several side pots with several people being All In at the same time. If there are not two player left who can bet, betting stops and all players turn their hands over.
