@odoaker2015 #207 The case pointed out in #191 by @Pdpgrgn is a bit different. First of all, the 7th player played no games, so there were in fact 6 players. Accidentally, in the first three rounds players A, B, C ended up all playing players D, E, F. That's possible because of the specific results. Now the problem is that the pairings in round 4 couldn't be made. E.g. A vs C & D vs F is possible, but B can't play E again. Etc. Otherwise there would have been a round 4.
