I think you are seriously underestimating the value of a good opening book.

Try an experiment by playing a program without a book against one that has a
book.  The program without a book will be absolutely slaughtered.

And a bad book is worse than no book.

I made a book before from 3 million games.  I told it to discard no moves at
all.  It still plays decent because it uses statistics.  But a program with a
good book will crush a program using my "silly" book.
