It is better to have _all_.  Crafty calls Eugene's probe code when the number
of pieces on the board drops to some value (5 if you have any 5 piece files
available).  If you don't have that file, I call his code, he returns "failure"
and we keep searching.  If you have them all, then _every_ call will be
successful and it is more efficient...
