What an amazing game! What are your ratings mate?

First win against an FM
Thanks for posting, but I must be missing something in this game. Why did your opponent quit? 25. Qe4 and he has good threats along the b1-h7 ddiagonal. Even pushing the Black f or g pawns forward to block this diagonal doesn't seem to help and only exposes Blacks king further.
