I think this is fairly well known to most of the people who have written
competitive programs. The art of preparing a computer book consists mostly of
picking lines the computer can handle (and preferably its opponents can't), not
picking lines that are actually good. Actually, this is true of competitive
human chess as well.

I am not very good at picking appropriate lines, either for my program, or for
myself :-(
