Secret Mittenberger Gambit!?

This gambit comes highly recommended from 2400 ELO Rybka.  I was kind of shocked to see a gambit recommended as a top line & especially from a computer!

Here's how it looks:

I get the feeling that I didn't play especially well; I felt like I was stumbling around since it was my first time playing this opening but I really liked the feel of what I call "shotgun knights" and they paid off in spades!

I could find almost no information about this gambit online, the only way I discovered it is because Rybka recommended it as the top line!
