If you have a *large* opening book, then most of the time it will navigate you safely past the initial development phase, and consequently the program can get away with not knowing very much about that phase. Of course you need to build the book from reliable source games and do whatever you can to make sure it plays towards the engine's strengths and so on. It's not clear to me how to do that without extensive analysis by the engine, so if a book is really large, the computational effort required to make sure it's quality might be prohibitive.
