Wow! Gaviota does well on this one! might be the only position on earth
that does better than Fritz, Tiger, Rebel and YACE! (PIV 1.4 Ghz 8mb hash)
Gaviota finds it in 0.3 seconds and holds that move. It shakes a little bit
because it finds that the score is falling but holds it tight (never changes its
mind) until ply 11 when it starts to fail high again.

Regards,
Miguel
PS: Gaviota is feeling cocky now :-)
