I was asked to post here, so here's my 2 cents
Wally didn't even know who his partner was in the first game. No matter how relaxed you are about leagues, if you're playing league, you always know who your partner is.
There's no proof that shows Wally knew it was a TUS game. Burden of proof is on the person making the claim, i.e. The people that claim it was a tus game and won.
I see no logs posted (which, btw, we ask for in the rules if I recall correctly) and I'm certain we have precedent where we told people to make sure everybody involved knew it was a league game.
Imo, void.
Couldn't be arsed to read the responses in this thread, since they didn't contain logs, so sorry for the laziness there

I did read the logs in the games, though.
