If you want it to be for two games just say that out clear. The way you wrote it is just in general any game in the B3. Seems you change the conditions when it suits you. O well not my deal anyway so.
I was clear in private, 2 games and against an inside attack and a minimum of FG so we have something to compare if it worked or no.
Anyway, let's be honest, the 2-3 doesn't work, if he wants to win the B3 the best for him is to play m2m ;)
