Requests a draw from your opponent. A draw means that you neither win nor lose your chess match - the game will be a tie. Ratings are affected, however, unless it was an unrated match.
If your opponent had offered you a draw, then the command draw (or accept) would accept the draw offer. To decline a draw offer, either use the decline command or make a move instead.
This command also claims a draw in the case of the 50 move rule or 3 times repetition. In the case of a draw being requested, the chess server will check for these conditions. If one of them is present, the game will be drawn even without the opponent accepting the draw.
