All the players were sober and tried to win, even after losing their chance of victory (well, almost all of them ;), and on the last day, some were playing for fun and suggested extending the tournament for one more round.
The alcohol-fueled chaos was only in the evening. When the games were going on, they would silence anyone who was shouting.
I understand that it's difficult to determine the strongest player in just 5 matches, but playing without a break for 2 months is stupid. And the championship is called CIS, not BO77.
Honestly, I'm so annoyed by this paternalistic analysis, that they all came there to drink, and no one even plays Heroes of Might and Magic, and doesn't even know how to play. Those who came to drink, drank, and those who came to play, played. And those who didn't come are losers xD
