  This is not logical IMO. I (myself) know some opening lines way beyond move
14. Particularly, I remember all my games, so I can easily repeat a won game.
Why should a program not be allowed to do the same?

  You can't. I can easily add a small nonsensical search for each book move
after move 14 where I say my program to only search for the chose book move for
15 or 20 seconds (or 4-5 in a fast game). The user will see the program is
searching the book move, and will see a PV, so there's no way to determine
whether it's a book move or not.
