... It did occur after the game had been played, but the conceding player didn't gain anything by doing it.
But he did. He got the satisfaction of having his friend go on to the finals. Wold he do the same for ANY opponent?
This point was made in our local group as well. The answer is no. Actually, after taking the dive in the 3rd round he went on to clobber his final opponent, who was somebody towards the bottom of the standings. That's another thing that bothered me about this. It not only unfairly benefitted the advancing player, it also skewed the standings so that an incredibly skilled player was taking on some folks toward the bottom. Floks that may have had a different outcome if they were playing others that were truly 1-2, not 2-1. The only game the conceding player lost was to the guy who ended up playing in the championship round against the guy who benefitted from the bye. And even then it was a really close game.
But no, he wasn't that generous to everyone.
