It is the _operator's_ responsibility to both make the move _on the board_ and/or claim a draw as directed by the program. That is the way it is done. It doesn't matter how the program says to do what. Because, as you have heard, at the current instant in time, only Crafty is capable of claiming a draw according to the exact wording in the FIDE rules of chess. I would hardly claim every other draw claim made in computer events is therefore wrong. >You say no, but this is a very seasoned TD. I concur at this junction. I've run _hundreds_ of tournaments myself. I'm hardly a new-comer to the idea of directing a tournament. And, by the way, _following_ the rules and interpreting them reasonably and consistently. > > >>> >>>I'm not saying they should throw the game either, but the ICGA IMO judged >>>correctly. >>> >>>Also, if it did claim 3rd repeat it must be claimed before the move is made and >>>this should apply to computers as it applies to humans. >>> >>>Backing it up is also wrong IMO it should be recognized on the spot! >>>If a computer can't adhere to FIDE rules, tough.
