thats just stupid, no matter what there's NO difference!
Two guys with no chances of advancing are stopping a tournament

Unfortunately the way tournaments are currently programmed on Chess.com, all games from the current round of a tournament must be completed whether they are relevant or not before the tournament can advance to the next round. Sorry for the inconvenience!
This tournament was started early this year and as you can see, there is still one ongoing chess game. Win, lose or draw, the same players will qualify to the next round.
