What do you mean, are the book move worse than what the program would calculate
itself? In this case the book must be bad, or not in tournament setting.
In the Fritz GUI's, it is a user setting if the book should be checked always or
not. But normally, transposing back as you say, should be an *advantage* when
the book is well done, consisting of reliable theory moves.
Some opening book, especially large one's generated from game databases, have
been critizised because of blunders, but also because they may be *too large*,
delaying the engine start to a point where the middlegame may be already shaped,
leaving not enough "game" for the program.
