Well I want to ask some simple questions to chess rules experts here:
1. Is King-Rook v/s King-Rook position is a good position to claim draw? I think yes, I can simply prove it. But ofcourse this will end with draw if no one does blunders.
2. In this position, I pressed the Draw button. 3 times in different move order. I am sure Chess.com didnt recognize it as Claim Draw action but Offer Draw so my opponent declined the offer.
As far as I understood from all above discussions, it is not possible to claim draw in Live Chess as you have to prove it so 3-Repeated and 50-Move Rules cannot be handled by GUI as well.
50-Moves Rule: If there is at least 50 moves played without any pawn move or piece sacrifice, game automatically ends with draw!
As some others have mentioned, this is the problem: it's not an automatic draw.
Generally, you have to claim every draw in chess. Stalemate is the primary exception.
I believe this is why the live chess draw button now reads "Draw" instead of "Offer Draw", to reflect that you'll claim the draw if possible, but otherwise offer a draw.
