The ScoreKBNK () routine in pl 67 does not quite work.  The following
2 lines have to be added just before the return (s); statement like so.

   s -= (8*taxicab(king1,king2) + 2*distance(Nsq,king2) + 
                                    distance(Bsq,king2)); 
   s += KingEnding[king1];
   return (s);


This seems to work fine now.  I've tested a few KBNK positions and 
with self play, gnu is able to mate itself in less than 35 moves most
of the time.

Regards.
