I have never seen this done but in chess I am prepared to offer
opening book odds. I will alow my opponent to bring any chess opening
book to the board, and he will be allowed to look up any opening in
the book and play any more he finds there.

It's done all the time. Some postal chess players use opening books
and others generally play without books. When a book-using player
plays a non-book-using player, the result is what you describe.
Obviously the books help, but are not decisive all by themselves.

Since I play off-beat openings not found in any book, I will give the
added stipulation that I will only play standard normal openings found
in MCO and other standard works.

In that case it will be harder for you to get a winning position in 15
moves. You're better off jumping out of book right away, even if it
means taking a worse position that you can beat your way back from.

If your offer includes "Chessbase odds" and is not limited to a
printed book, you're somewhat worse off, I'd expect.
