Can you tell us how it loses? I couldn't see it.

Here's what my modified Crafty thinks after a while:
15-> 110:10 0.09 1. Nxf5+ gxf5 2. Qh4 Re4 3. Red2 Rh8
4. h3 Qd8 5. Rd4 Qc7 6. Kg3 Kg6 7.
Kh2 Rg8 8. a4 Rxd4 9. Rxd4 Qc5
So it likes Nxf5 more than other moves, but it's barely more than a draw score.
And the score has gone down on almost every iteration so far. I'll see what it
is after 16 and maybe 17 a bit later, if I can stand to let it run that long. :)
