If a position is repeated for the third time and it is my move, I may claim it instantly, and call the TD for verification. If the position is repeated for the third time _after_ I make my move, then I write the move down, but do not make it, and call the TD over for verification. My opponent has no input. If you want your chess engine to look _really_ stupid, then let it play through a draw by repetition and lose. Or just play an infinite game, hoping your opponent will screw up. You miss one important detail, since this is related to _computers_ only. You have _already_ repeated the position once and your opponent did not blunder. Do you _really_ think that if you repeat again and don't claim the draw, that he will blunder this time around? If so, how many cycles before you are convinced that he won't? That's why it is a 3-fold repetition and not a 2-fold repetition. Once lets you get back to an old position and try a new move. Twice says "you had your chance." In the ongoing discussion here, the computer said "this is a 3-fold repetition". That's good enough for any reasonable TD...
