The black pawn zig-zags it's way across the board and promotes. :lol:

Analysis by Naum 4.1 (single):

1.Bb5 a5 2.Bb4 axb4 3.Qa3 bxa3 4.Nb2 axb2 5.Rc1 bxc1Q 6.Rd3 Qf4+ 7.Ke6 Qe4+ 8.Kd7 Qxb7+ 9.Nc7 Kxh7 10.Rd6+ Kh8 11.Rh6+ Kg7 12.Rg6+ Kh8 13.c5 Qb8 14.Rg8+ Qxg8 15.Bxg8 Kg7 16.Na6 Kh6
+- (#23) Depth: 35/53 00:00:34 64232kN

But I don't trust either engines's numbers...

I don't either. I can't get any two engines to agree after 1.Bb5 a5 2.Bb4 axb4 3.Qa3 bxa3 4.Nb2 axb2 5.Rc1 bxc1Q 6.Rd3 Qf4+. :?: :lol:
