Good point. I hadn't considered this since it was fairly apparent that in order to make a draw by repetition of position claim, the repetition must have already occurred (the last move being made by the opponent) or the move intended by the current side to move must lead to the third repetition. But from the point of view of the computer, it is similar to the 50 move rule. If there is a move that is possible for the moving side which leads to the repetition and that side claims draw by repetition, I doubt very many computers will understand this (or play it this way) unless the move is actually made (regardless of which side is to move). I doubt many programs are set up to check and see if one of the legal moves from the current position allows a draw by repetition and will therefore grant the draw to the other side (or will claim a draw itself without making the move). Good catch! KarinsDad :)
