The Chess 50 move rule is a fundamental rule in the game of Chess. It provides a way to end a game when there has been no progress for a long time. This rule is designed to prevent the game from going on forever, as it can in some cases.
The Chess 50 move rule states that if no pawns have been moved, no pieces have been captured and no check has been made in the past 50 moves, the game is declared a draw. If either player requests it, the game is stopped and scored as a draw.
