Amy seemed to want to take that pawn, so did the Dos Comet, unfortunatly with
Comet, I fell asleep and my computer's "energy saving" thing shut it down at 45
minutes, but on my computer it really wasn't going to search deeper than 13
(probably).  I had the hashtable at 32mb, I had to bail out on the search
because I wanted my computer back.

I didn't run it past Crafty, I figure someone with a newer computer will without
a doubt do that.
