Do _not_ use that.  'small.txt' is the text we used for Cray Blitz.  If you
look carefully, you will find every variation from MCO10, which I typed in by
hand all by myself.  You will find a lot from MCO11/12, plus BCO, ECO and
other stuff typed in by Gower.

Those are not games... there is _nothing_ there to indicate which lines were
good and bad...  so you will get _killed_ with that.  We used to manually ass
! and ? to the lines we wanted to play/avoid in CB, but I stripped all that out
when I first worked on Crafty's book...

that book will have you playing lots of totally random stuff that will get you
in a world of trouble...
