Oh man, and you wish to organize your own tournaments
Side Pot (example):
Player A have 100$
Player B have 300$
Player C have 200$
If they all go all in player A cant win more than 300$, and player C more than 400$ in any situation player B will return 100$ back, but when pl B will have 2nd hand he will return all his 300$ and pl C end the game. This is side pot!
