They assume that it is obvious that they use the books that are sold with the
programs.

I saw games and I know that they use the books of the programs.

Sometimes the books are counter productive.
I saw a game between fritz5(Pentium200)  and Mchess6(P90) that was a draw by
book(firtz5 was white).

I think that fritz5 had good chances to win without book.

I am interested in longer time control because I use the computer to help me in
my correspondence games.
