Make a book named nunn1 intended for position no. 1 from nunn.pgn or nunn.cbh. 2. Import all the 10 games to the book, and modify the book moves by making every move on game no. 1, the main move. (right click on the move and choose main move say from 1. e4 c5 etc.) 3. So for opening position 2 make a book named nunn2 etc. Under book option use optimize and then choose minimum games = 1 for each engine. Regards, Dinan
