Coach Vas produces an 18 move crush!

I lost to my opponent as Black in an earlier round of the team4545 chess league played on ICC. I knew he'd prepare for my usual Trompowsky so I played what is for me a new idea against the Dutch. The book doesn't recommend taking on g4 and now we have proof. So sit back and enjoy! My opponent had 41 minutes left on the clock when he resigned.
