What Is The 50-Move Rule?
The 50-move rule states that a player can claim a draw in chess if no one moves a pawn or captures a piece for 50 consecutive moves. In this case, a move consists of each player moving a piece once.
In over-the-board chess, a draw is not mandatory under the 50-move rule. A player needs to claim it. However, an arbiter can intervene and declare a game drawn if no one makes a capture or moves a pawn for 75 consecutive moves.
Instead, online games automatically end with the 50-move rule. This way, players who want to make a draw don't need to worry about counting the moves.
Why Is The 50-Move Rule Important?
The 50-move rule is important for keeping a player who has no chance of winning from playing on. Without this rule, a player could try to win a drawn game by annoying or tiring out their opponent, encouraging them to resign.
The 50-move rule can also save a player from losing on time. In the video below, you can see an example of GM Jorden van Foreest securing a draw with less than one second on his clock, thanks to this rule.
Because of the 50-move rule, knowing how to convert a winning endgame effectively is very important for a chess player. Players can often reach an endgame that is objectively winning for one side. However, the other player can claim a draw if the side with an advantage can't win in 50 moves.
This happened during the 2018 Women's World Blitz Championship when former women's world champion Tan Zhongyi couldn't deliver a checkmate with a knight and bishop.
Examples Of 50-Move Rule Draws
One notable example of a game ending in a draw because of the 50-move rule happened between GMs Anatoly Karpov and Garry Kasparov. In a complicated game, Karpov had a material advantage with three minor pieces for a rook. Despite the material advantage, Kasparov defended well and held off Karpov. The game ended in a draw on move 114 because of the 50-move rule.
Another notorious example of a game ending in a draw because of the 50-move rule happened between GMs Jan Timman and Christopher Lutz. The players reached an endgame of a bishop and rook against a rook, with Timman having the material advantage. That advantage, however, was not enough for Timman to win the game. Ironically, Black's last move would force a rook exchange, which would also force a draw.
