aha... you are thinking of producing one game for *each* alternative
in the book? I'm looking at doing something much shorter, as I did in
Cray Blitz... your idea will certainly work, but it will produce a
really large pgn file I'm afraid... the CB format was more of a "tree"
type format without having 1. e4 in the file thousands of times...
