What is the fifty-move rule in chess?
I · Intermediate · Winning and drawing · 4 of 7A player may claim a draw if each side has made 50 moves in a row without any capture and without any pawn move. Every capture and every pawn move sets the count back to zero. At 75 such moves by each player the game is drawn automatically, with no claim needed.
How it works
- Fifty moves: "the last 50 moves by each player have been completed without the movement of any pawn and without any capture".
- A claim is needed: by the player whose turn it is, either after the fiftieth move or by writing down the move that will complete the fifty and telling the arbiter.
- Reset: any pawn move or capture starts the count again.
- Seventy-five moves: the game is drawn without a claim.
- Checkmate comes first: if the seventy-fifth move gives checkmate, that stands.
- Checking the claim: is the players' job, under the arbiter's supervision, using the scoresheets.
- Wrong claim: two extra minutes to the opponent, and play continues.

Tricky cases
Forty-nine moves have passed and a pawn moves one square. Where does the count stand?
At zero. A pawn move restarts it.
Fifty moves have passed and nobody claims. Is the game over?
No. The fifty-move rule needs a claim. The game goes on until someone claims, or until 75 moves bring an automatic draw.
Does "fifty moves" mean 50 turns in all, 25 each?
No. It means 50 moves by each player.
In a blitz game nobody is writing the moves down. Can the rule be claimed?
It depends. Players keep the right to claim, but without a scoresheet they depend on the arbiter's record or on electronic recording of the game.
Why the rule exists
Captures and pawn moves are the only moves that cannot be undone, so a long run without either means the position is going nowhere. Fifty moves is long enough to win every standard endgame that can be won, and short enough to stop a player from grinding on in hope of a mistake.
