Just lead it into the Evans Gambit or some other sharp opening where a mistake
is hard to see and quickly fatal.

Your point is clearly "A empty book contains no bad lines, since all the lines
are missing."

My response is: "All the lines it contains are bad, since they cost the program
time and do not avoid places where this particular engine fears to tread."

Imagine a game of 50 moves and 25 moves are in book.  You have a 50% time
advantage.  It *should* only be worth 50 ELO or so, but it seems it may be worth
much more than that.  That is because the really good books will have carefully
researched the best lines and include only the highest quality games.
Therefore, many bad decisions are weeded out.

Books are important, and a lot more important than most people think.  Except
Vincent, who is rabid about the books.
