accept a Draw or finish the game


If a player lets the clock tick down needlessly, it is against chess.com policy. You can report them for it, and I have done that at least once before.

Why would you accept the draw? you were in the right in that situation
He probably didn't want to wait for so long.

The guy is probably toxic. He doesn't like that he is losing and wants to get a draw. He gets upset that he is going to lose and decides to run out his clock to be as annoying as possible.
REPORT HIM IMMEDIATELY. It should not be tolerated and they should get disciplined for it.
