but to make that clear, if you know nothing at all about openings, you
may be completely lost in CA, and should prefer Chessbase, which may
be much more suitable for players below 1700 ELO ...

well for players below 1500 or so i would recommend Bookbuilder 4
which is much cheaper than ChessBase (and even Bookup) anyway.. Recently
made more userfriendly, especially for lower ranked chess players; have fun at:
