You select your book in the GUI Preferences tab. In the Book Options tab you can limit the number of moves as well as select random openings per game,etc.
OK, I had seen that, but could not find the signification of
* checking or not the box "Use GUI remis Book" (I checked)
* what are sequential per cycle (I checked that) or per game, random per cycle/game (has Matthias explained it somewhere?)
* I left BookLine Offset at default 1 and Book Moves at default 2. Obviously that doesn't limit the number of moves (so how to do to limit, say to 10?)
Indeed, I found the books inside the ChessGUI download package, thanks!!!
Did get the Silver 2011.cgb, but no dice for Picasso.cgb (maybe there is another link?)
Thanks anyway, for all the help, Graham...
