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
4. Kb3 Ra5 5. Bd6 Rb5+ 6. Kc2 g5 7.
Nd3 Nc4 8. Ne5 Rb2+ 9. Kc3
14 1:59 -1.11 1. cxb6 axb3 2. Kb2 bxa2 3. Kxa2 Nxb6
4. Kb3 Ra5 5. Bd6 h6 6. Nd3 Rf5 7.

15 4:56 -1.07 1. cxb6 axb3 2. Kb2 bxa2 3. Kxa2 Nxb6
4. Kb3 e5 5. Bc5 Nd7 6. Nd3 Ra5 7.

15-> 6:39 -1.07 1. cxb6 axb3 2. Kb2 bxa2 3. Kxa2 Nxb6
4. Kb3 e5 5. Bc5 Nd7 6. Nd3 Ra5 7.
Bb4 Rb5 8. Bg4 b6 9. Bxd7 Bxd7
and after 1. cxb6 Crafty says:
13-> 1:25 1.05 1. ... axb3 2. Kb2 bxa2 3. Kxa2 Nxb6
4. Kb3 e5 5. Bc5 Nd7 6. Bd6 f6 7. Bg4

4. Kb3 e5 5. Bc5 Nd7 6. Nd3 f5 7. Bh5
g6 8. Bf3 Ra5 9. Bd6
14-> 3:24 0.95 1. ... axb3 2. Kb2 bxa2 3. Kxa2 Nxb6
4. Kb3 e5 5. Bc5 Nd7 6. Nd3 f5 7. Bh5
g6 8. Bf3 Ra5 9. Bd6
15 6:44 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
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
