Fritz on the DS

Hey All,

I've owned Fritz by Chessbase on DS for years now, but I was very, very young when I got it (like 12?) and my chess SUCKED back then, and I got clobbered by Fritz. Today, i said "Screw it" and decided to play rated games vs Fritz on it's highest strength (apparently the ELO is 2320) and the description was it was for grandmasters or something. I got beaten a few times in our games (15m, 0 increment) but I just had a game which was WILD, and I cannot rap my head around it. Here's the game:

Moves with extended analyses have moves I thought were mistakes, but weren't. Moves with analyses next to them AND a ? or ?? shows I DID analyse them, and couldn't understand why. Any ideas?
