What are the poker side pot rules and how do they impact the outcome of a hand?

In Poker, a side pot is created when one or more players go all-in and have different amounts of chips. The side pot is separate from the main pot and is only contested by the players who have contributed to it. The side pot rules impact the outcome of a hand by allowing players with more chips to continue betting and potentially win more money, even if they cannot win the main pot. This can lead to complex strategies and decisions during a hand.
