If I had known earlier of your indeed brilliant plan, I would have not advanced upon German soil so soon. It was a very good plan! However, I'm afraid the cards are already played.
As for the attack upon Silesia being a misplay, I beg to differ. :P I would not take centers that my allies require. My armies are not there to simply take centers: first and foremost, they are there to support the Northern advance of my allies. The fact that my country is the strongest out of our alliance is due only to the fact that I had an extra unit to begin with. Even as I grow in strength, Austria and Italy grow in strength.
Long live the Triforce Alliance.
