It could say : "The game is a draw by repetition" In case the position on the board is a 3rd repetition it should say nothing else . In case the 3rd repetition position will be reached by a certain move it could say : " I intend to play 49. Rc8+ and claim draw by repetition ." That ICC and WinBoard/XBoard currently don't support doing it like this doesn't mean it can't be done at all . An enhancement of the WinBoard protocol adding a "claimdraw" as Miguel A. Ballicora suggested would be a good start . > >I have seen that scenario played in major WC type events. I once watched >Korchnoi do exactly that in a US Open game... He made the move on the board, >wrote it down, claimed a draw, and got the arbiter... I don't get your point here - so Korchnoi did wrong ..; the rule explains exactly how it should be done . pete
