Goette,
After, 2....bxc5, all engines plays 3.b6:
Crafty 16.5 T.... Depth Evaluation
13 -1.29
14 -0.92
15 -1.05
Fritz5.32 ....... 15 -0.56
16 -0.22
17 -0.47
Genius 6 ........ 11 +0.09
12 +0.09
13 +0.09
I forgot to write that the study of Jeremiah 2...bxc5
helped me to find 2...dxc5, therefore jeremiah
was showed that 2....bxc5 was better for white,
and you wrote that the position was drawn.
This endgame is really pretty!
Best regards,
Paulo Soares
