Players A, B, C and D each are competing for the pot. Player A has 160 in chips. Player B has 120. And both Players C and D have 50. C and D can call any bet made by either A or B for 50. A can call any bet made by C or D, and 120 of any bet made by A. Thus, player A has 40 that cannot be bet in this round. Suppose that B bets 80 in chips. Player C drops. Player D calls for 50, that being the most that he can. Player A calls the entire bet, putting in 80. 50 goes into the main pot, and 30 goes into a side pot with B. The winner of the hand (either A, B or D) will get the primary pot. In addition, if A's hand is better than B's, then A will get the 60 in the side pot. If B's hand is better, B will get the 60.
