Seventy-five-move rule

The seventy-five-move rule is an automatic limit for positions that continue without a pawn move or a capture. Once each player has made at least 75 consecutive moves under those conditions, the game ends in a draw even if neither player claims it.

Any pawn move or capture resets the count. The 75 moves mean 75 actions by White and 75 by Black, so the sequence covers 150 individual turns.

The key difference from the fifty-move rule is procedure: at 50, the player with the turn may claim; at 75, the result is automatic. There is one express exception. If the final move of the sequence gives checkmate, meaning the king is attacked and has no legal reply, checkmate takes precedence and the game is won.
