"is your setup right?"

I hvae 5 pieces TBs and have used under Fritz 8 8 MB Cache. What is here wrong?

On a 2 Ghz Machine S9 must after few seconds saw that the line with BxB is
wrong! Or not? The Pawn endgame was losing - very short! Poor for fast
Computers!

Was the setup from my opponent right?

All in all, other engines are here much better than Shredder 9 !!
