Many of them use very deep books, many of them do not, and it varies across the board. Most of the stronger personalities use a deep book, but not all. Most of the lower personalities have no book or a book that only goes a few plies, but not all. There are personalities rated less than 600 who use the CM8000 book! The point is variety. As for the GMs, their books are based SOLELY on a database of their games. So if there are no games of a certain line in the database, then that line will not be present in the opening book. This could be modified, of course, if some concrete examples could be given. I doubt, though, that the "human" personalities are going to be changed in any way. jm
