The term 'sidepot' refers to a secondary pot in poker games where players can compete for additional winnings, separate from the main pot. This occurs when one or more players go all-in while others continue to bet, leading to the creation of a sidepot that only certain players can win.

Understanding sidepots is crucial for players as they can significantly influence the strategy and outcome of a hand. When players are all-in, any additional bets made by players who are not all-in contribute to the sidepot, offering further chances to win even after contributing to the main pot.

In many games, particularly in Texas Hold'em, managing sidepots can be complex but rewarding. Successful players must be adept at calculating their odds and understanding the dynamics of both the main pot and any sidepots to maximize their potential returns.
