I think your analysis below might be flawed. After the following:
Bxe3+ Kxe3 c6 dxc6 a4, crafty thinks Kf4 is winning for black, while the
suggested move loses for black and allows the e6 trick to work. Kf4 seems
to allow the black bishop to stop the pawn just in time:
16-> 28.72 -3.03 3. ... Kf4 4. e6 Kf5 5. e7 Bg5+ 6.
Kh5 Bxe7 7. a5 Bc5 8. Kh6 Ke4 9. Kg6
Kd4 10. Kf7 Kc4 11. Ke6 Kb5 12. Kd7
Kxa5 13. Kxc6
As a result, it will not play Bxe3+ to start things rolling as it believes
that loses outright...
