NeuroDoc, if you can get check forever, then at least one of the following is true: <p>* You can get checkmate. (But in that case, why go for the draw?) <p>* You can force the same position to repeat three times within 50 moves, which gets you a draw. <p>* You can force 50 moves to happen without a capture or a pawn move, which gets you a draw. <p>If the group plays without an official 'perpetual check' move, sane players will agree to a draw in a perpetual check situation. <p>Incidentally, I got to this page by googling for 'perpetual check' while I was inflicting it on my Mac in Apple Chess. It appears both that Apple Chess does not recognize perpetual check and that you can get it to crash by triggering the 50-move rule. ;) In this situation, the computer had a queen and three pawns, and I had just a queen, with which I kept the computer in check without allowing it to block with a pawn or retreat behind the queen. I doubt I could have forced a draw by three repetitions; although I could force him to stay on one side of the board, the king had a lot of space to roam.
