I do think chess.com could better deal with stalling (against rules of site). I have seen other sites offer a "claim draw" or "claim win" option in such clear cases
Chess.com already does that for abandoned games, but automatically. "Other sides" don't give you a win if the player is still connected.
It would be an improvement if they found a way to grant the ability to claim a win even when an opponent is still connected in my opinion. Something like a "You still there?" popup after however many seconds without making a move when down however much material.
I'm sure there a better ways too. Maybe some sort of premove to victory, where after showing the premove all the way to mate, you don't have to wait for your opponents move to trigger the premove, and the game automatically ends.
But they already grant you a win.
Yes, but as mentioned it could take half an hour to do so.
The whole point is to avoid stalling, which goes against the rules of the site. Hence those suggestions, which would take aim at the rule breakers during the game, rather than afterwards
.. 5 hours and no post.. God bless all of us
