Hello Leonid,

I'm afraid, your CD is a bit too hard for Chest: after 6.4 hours on a K7/600
with 350MB hash it still just says "No solution in 9 moves."
More depth will last a bit too long, so I stop here.  Sorry.

EBF is not very bad, but also not good enough:

 depth  time     EBF[T]              EBF[N]
#  1      0.00s                 0kN           0.87          1-         0
