What is the rule in chess when the king remains?
Article 5 of the FIDE Laws of Chess gives the ways a game may end in a draw, and they are detailed in Article 9: The fifty-move rule – if in the previous fifty moves by each side, no pawn has moved and no capture has been made, a draw may be claimed by either player. The draw is not automatic and must be claimed if the player wants the draw. If the player whose turn it is to move has made only 49 such moves, he may write his next move on the score sheet and claim a draw. As with the threefold repetition, the right to claim the draw is forfeited if it is not used on that move, but the opportunity may occur again.
