It was more your poor GS that explains the result. By the way, did you know that all B3 games are played with full enthusiasm? Because I don't understand your TIE against Dartreb...
My quite poor GS didn't help indeed but his was hardly better.
I actually didn't know this rule had changed, Patrick told me the same thing when he saw i was playing tie vs. Dartreb. It's my fault - not searching for excuses - but it would be great to mention it somewhere in the rules (unless i didn't search well.)
That said, I believe I would have played tie with or without the B3 game. I was surprised that @Dartreb played normal as he had nothing to win. I read your comment, fair enough... I haven't won at yours for ages anyways so i usually consider that game as a loss each season

I still would have lost playing normal so i don't regret my choice, Dartreb was just better.
