You used an engine for analysis purposes. That is an important application.
Many people do not only play a game against a computer, but use it as a tool.

Now you observe a problem with Fritz. I don't trust most of the available
engines. They have unpredictable holes. May be you would better use Crafty, as
Crafty has (at least to my knowlege) only one big hole - the null move hole.
But if you look at a position you may get an opinion whether this may be a
problem or not.
Here some output from Crafty for your position, wtm.

               13->   1:07  -1.16   1. cxb6 axb3 2. Kb2 bxa2 3. Kxa2 Nxb6

                                    Bb4 Rb5 8. Bg4 b6 9. Bxd7 Bxd7
and after 1. cxb6 Crafty says:

                                    4. Kb3 e5 5. Bc5 Nd7 6. Bd6 f6 7. Rd2
                                    Ra6 8. Bg4 b5 9. Re4 c5 10. Bxd7 Bxd7
               15->   7:52   1.04   1. ... axb3 2. Kb2 bxa2 3. Kxa2 Nxb6
                                    4. Kb3 e5 5. Bc5 Nd7 6. Bd6 f6 7. Rd2
                                    Ra6 8. Bg4 b5 9. Re4 c5 10. Bxd7 Bxd7

This looks pretty good.
By the way, I'm not the only one using crafty for analysis purposes.
Kind regards
Bernhard
