Joseph is away for two months, I'm not sure he will contact you
soon.

There are already a few "databases" with positions of books. I put
all of Kit Woolseys "New ideas" into Frank Bergers Bgblitz
(www.bgblitz.com) and just work on Roberties "501". Also I try to
compare all quiz positions of www.gammonline.com with gnubg answers.

And I bet that al the good players have thousands of reference
positions including rollouts made by jellyfish, snowie and now also
(hopefully) made by gnubg.

Gnubg starts with 0-ply. What kind of program are you working on?
