What are the rules and implications of side pots in a poker game?

In Poker, side pots are created when one or more players go all-in with different chip amounts. The main pot is for the player with the highest chip count, while the side pot is for the remaining players. The implications are that players in the side pot can only win that pot, not the main pot. This adds complexity to the game as players must strategize and manage their bets accordingly.
