Bigger is not always better.  I think crafty has gone to a much narrower book
for tournaments that it used to use.  Most opening books have bugs in them, and
many of the really big books have a huge number of bugs in them.

An excellent opening book can give you a very decisive advantage.

If you could make a very large one and yet keep the high quality, it would be
dominating.  You would put your opponents under a lot of time pressure, since
you saved it up front with the book.
