In chess, a "fortress" is a defensive formation or setup that a player creates to prevent the opponent from being able to make progress, often in a situation where one side is at a material disadvantage but can effectively safeguard against losing. This concept is typically relevant in endgames, where one side has an inferior position but can set up a configuration of pieces that makes it impossible for the opponent to break through and force a win.
