Estragon is correct, but there is something I wonder. If you are the player that has the last move of the repetition, can you claim the draw before you make the move that fullfills this repetition? This would make sense, but it would be nice to get it confirmed.
not able to draw the game
Thank you I did'nt know that I had to claim it. I just thought the system would grant it automatically after repeating moves. But I remember a few games where the "game is drawn by repetition" dialogue box came up without me claiming it. So I guess the opponent must have claimed it right?
One other clarification I need is on the pepetual checks. How many checks to draw? can it be claimed or only on agreement with opponent?
@superzaldor : I don't thimk you can claim it before repeating the position 3 times. Maybe I will try it one of these games and see.
In that case you will risk that your opponent makes a different move (which may even be a premove) that breaks the repetition even if it was fullfilled - before you manage to claim the draw and you will lose the right to do so.
In on-the-board tournaments this problem doesn't exist because you have to press the clock manually. As far as I understand it's common to claim the draw verbally while you make the move, and I've heard that you can also just note the move that fullfills the repetition on your score sheet and claim the draw immediately.
Superzaldor, no you can't, and it's a big error in chess.com. That means your right to claim the draw can be stolen from you by your opponents pre-move or conditional move.
Claiming a draw just before three-fold repetition is a FIDE law of chess, but pre-moves and conditional moves aren't. Funny how a non-FIDE rule overrides an official FIDE rule.
3 repetions of the position is a draw right? I repeated a position in one of my games more than thrice but still the draw was not declared. Do I have to claim it ? or is it because I was short of time I am destined to lose that game?
I ended up losing the gamne on time in the end.
