Remember Cray Blitz is not the same as Crafty by any stretch.  We were using
a horse of a machine when Larry and Don sat down with me to run the test
positions.

I will have to try to find the old output.  I don't remember it failing to find
a single answer, although some of them are really questionable as to whether
they are the best move or not.  Just because Fischer played a move, for example,
does _not_ make it the best one possible.
