Fifty-move rule
The fifty-move rule lets the player on move claim a draw once fifty moves by each side have been completed with no pawn move and no capture, so a game that makes no progress cannot run on forever.
Think of a counter that starts at zero and counts moves by both sides. Every pawn move and every capture sends it back to zero. If it reaches fifty moves each, which is one hundred half-moves, the player whose turn it is may claim a draw. The rule matters in long endings where one side has the edge but cannot make progress, such as a rook ending with the pieces shuffling. For the stronger side it is a deadline. Before the count runs out you need an irreversible change, meaning a pawn push or an exchange, or a way to force one. For the defender it is a resource: if you can hold the position together for fifty moves, the clock rescues you. The Laws make no exception for endings that theory says need more moves, so a player trying a long technical win has to keep count. As with repetition, the claim is made either when the fifty have just been completed, or beforehand by writing the intended move and telling the arbiter. A wrong claim gives your opponent two minutes, and touching a piece loses the right for that move. If nobody claims and the count reaches seventy-five moves each, the game is drawn automatically.
It sits close to Draw by agreement. A draw by agreement ends the game with a half point each when both players settle on a draw, which the Laws allow once each has made a move unless the rules of the event restrict it.
Compare it with Seventy-five-move rule. The seventy-five-move rule ends the game in a draw automatically when each player has made at least seventy-five moves without a pawn move or a capture, unless the last move was checkmate.
It sits close to Fivefold repetition. Fivefold repetition is the rule that a game is drawn automatically, with no claim needed, once the same position has appeared at least five times.
