What is the 50-move rule in chess?

The 50-move rule states that a player can claim a draw if no pawn has been moved and no capture has been made within the last 50 consecutive moves by each player.

Does the 50-move rule happen automatically?

In online chess, the server usually declares the draw automatically. In over-the-board tournaments, a player must actively claim the draw based on their scoresheet.

Why does the 50-move rule exist?

It exists to prevent games from continuing indefinitely when a player does not know how to checkmate but refuses to agree to a draw.

What Is the 50-Move Rule?

The 50-move rule prevents chess games from going on forever. If 50 moves pass without a pawn move or a capture, the game can be claimed as a draw. Understanding this rule is vital for endgames, ensuring you know when to hurry your checkmate and when you can claim a draw in a losing position.

The Official Rule

The game can be claimed as a Draw if the last 50 moves have been played by each player without:

1. Any Pawn Move
AND
2. Any Capture

This means if you are just shuffling your King and Rook back and forth, the counter is ticking. However, the moment a pawn moves or a piece is captured, the counter resets to zero.

Why Is This Important?

This rule usually comes up in endgames where one side is trying to checkmate with limited material (like King + Rook vs. King).

For the Defender: If you can survive for 50 moves without getting checkmated (and without any pawns moving/captures), you escape with a draw!
For the Attacker: You are "on the clock." You must prove you know the checkmate technique before the limit is reached.

Does It Happen Automatically?

Online (Chess.com / Lichess): Yes. The server tracks the moves and will automatically end the game as a draw once the limit is reached.
Over-the-Board (Tournaments): No. You must keep score and claim the draw to the arbiter. If you forget to claim it, the game continues!
