Other Draws
Part of the Fundamentals section of Coddy's Chess journey. Lesson 30 of 41.
Stalemate is not the only way a game ends level. Chess has a small family of draws, and knowing them lets you rescue lost games, and stops your won games from slipping away.
First, threefold repetition: if the exact same position appears three times with the same player to move, either player may claim a draw. Its most dramatic form is perpetual check, where a losing side checks forever and the defender can never break the loop:
White is a whole queen down, but Black's king never rests: Kh7 is forced, then Qh5 check, Kg8, Qe8 check, round and round. The third time the position repeats, White claims the draw.
Second, insufficient material. Some armies simply cannot deliver mate no matter how badly the opponent plays: king against king, king and bishop against king, king and knight against king. The moment the board reduces to one of these, the game is declared drawn:
King and bishop cannot checkmate a lone king: no sequence of legal moves ever produces mate, so the game is drawn on the spot.
Third, the human draws. Players may simply agree to a draw at any moment; you will see one offered with a quiet 'draw?' after a move. And there is a progress meter: if 50 moves by each player pass with no capture and no pawn move, the game is drawn, proof on the scoresheet that nobody is getting anywhere.
