19.03 on a Cel 1.3ghz. From the 4th move position as White:

[D]8/4P3/2B5/8/8/6p1/5kP1/5b1K w - - 0 4

After a while and going to 22 ply, Crafty still wants to promote to a bishop:
22/408
4. e8=B Bd3 5. Bb5 Be4 6. Bec6 Bg6 7. Bf3 Bf5 8. Bbc6 Bg6 9. Bfe4 Bf7 10. Bd7
Ke3 11. Bef5 Bb3 12. Bc6 Kd4 13. Bb5 Ke5 14. Bbd3 Bd5

Thanks for trying those other engines Jamie, it seems others have trouble as
well.
