The tournament still lacks regulations; the criteria for advancing from the group stage in case of a tie have not been defined. Essentially, the judges have no tool to resolve this issue. By the way, if the head-to-head result is less important than the overall standings, then this game was irrelevant.
You are wrong. In this case, the overall standings are what matter. If Defiant wins, I advance, and if Putin wins, they both advance. There is only hope that Defiant won't give up a game that is insignificant for them in order to favor a fellow player.
