that is only a start... it doesn't make crafty play like a dummy.  It might
get it into a dummy position, but against all but the best players it will take
that dummy position and rip you to pieces with it...

And such a book really wouldn't help as much as you'd think.. even with the
enormous book (1.5M games) I still see many games where crafty is out of book
by move 8 or less..

this is my thinking as well, except that it could have a few pre-defined
personalities (IE (1) can't play endgames;  (2) doesn't recognize kingside
attacks;  (3) you name it... (4) etc...)

Of course, users can always develop their own, and I suppose I could add a
'database' they could be named/saved in...  which would make sharing them
even easier..
