This isn't all that complicated. I'm sure chess.com could figure out a relatively intuitive interface. The alternative is leaving a not-insignificant problem in place, especially when conditional moves or pre-moves are at play.
Yes, I can see the issue if your opponent uses conditional moves to prevent the claim.
Yep, once I "cheated" like that when I realised it's actually winning for me.
@Rsava::In OTBs ,if before playing that move, arbiter didn't accept,then after making that move, if that's 3 fold rep. arbiter hv to accept.in here,i offered draw bt since the game is still on ,made the move hoping to claim draw . bt no "claim draw/offer draw" is there...if there is,then should i not claimed that.
