Choose the PGN file you want to load, then a dialog will come up asking you for the criteria with which the moves will be weighted. As an example, for the GM books that I created I used the "Frequency" criteria, 40 depth, and minimum moves of 1 -- if the GM played it in real life, then the book should have it. For a stronger book, you should probably use minimum moves of at least 2 to prevent blunders. And you might want to choose the "Wins" criteria instead. jm
