On the other hand, I have become very curious about his program.  It seems to
always do incredibly well on mate finding and problem solving.  The same is true
of Little Goliath, and either LG or Crafty is the strongest free program in the
world.

I suspect his program will do very well if it is ever released.  Or it might be
another Ferret to tease us forever.
