Draw by agreement
In chess, a draw by (mutual) agreement is the outcome of a game due to the agreement of both players to a draw. A player may offer a draw to his opponent at any stage of a game; if the opponent accepts, the game is a draw. The relevant portion of the FIDE laws of chess is article 9.1. The vast majority of drawn chess games at the amateur club/tournament level and higher are draws by mutual agreement rather than the other ways a game can be drawn (stalemate, threefold repetition, fifty-move rule, or impossibility of checkmate) (Schiller 2003:26–27).
The FIDE laws state that a draw should be offered after making the move and before pressing the game clock, and marked in the scoresheet as (=) (see Appendix C.13). Draws made at any time are valid, however. If a player makes a draw offer before making their move, the opponent can ask them to make their move before deciding. Once made, a draw offer cannot be retracted, and is valid until rejected. A draw may be rejected either verbally or by making a move (the offer is nullified if the opponent makes a move). The actual offer of a draw may be made by asking directly "Would you like a draw?" or similar, but players frequently agree to draws by merely nodding their heads (Schiller 2003:26–27). In international chess, the French word remis is an offer of a draw.
