[MMH6 TOURNAMENT ON] 6th attempt.

I can suggest the following: "Either a duel is held, or there will be a minor violation of the Swiss system - both players are disqualified."

Disqualifying players when there aren't that many of them left is not the best idea. At least, because of just one game. In the first tournament, [7x]Scorpion didn't play a single duel - in such cases, it's necessary to exclude them. But if a player simply missed a game, it's worse for them.
