I see your point -- for guidance and learning on the human side rather than for computer program improvement. Certainly an interesting idea. > >P.S.

This became version 2, 3, and 4. Later it seemed wise to go to bitboards and that's when version 5 came out. John was a manager in an IC lab in HP in Ft. Collins, Colorado. I don't know if he's retired or what nowadays. Always an interesting commentator and programmer in the computer chess scene. Stuart
