One of the nice things about Chessbase interfaces is that they'll allow you to
play "rated" games, where they'll allow you to get a rating as calculated
against a series of games against the program.  It's a real ego flattener, it
does not allow you to take back any moves (the only honest way to play Chess),
and though I have not used the "rated game" feature in my Extreme program for a
long time, I don't really think it even lets you use Window's multi-tasking
either, but I could be wrong about that.

I've seen very few programs that won't let you take back moves altogether, Nero
5 doesn't as I recall, but I'd like to see more programs not allowing it, OR AT
LEAST having a setting that can only be changed in a peogram initiation file
that went something like:

takeback = 1  or  takeback = 0  (or true, false or on, off etc.)

This would discourage cheating, and I say this realizing that the average
program can out calculate me many times, and I know that I'll never beat my
favorite programs going full strength.  But it's just that irritating matter of
principle that creaps in where I think you should not be allowed to take back
moves (even though I _do_ take moves back against a program)
