wise to get into the *habit* of taking back moves.

That's what you do when analysing a game.

Old habits die hard, and this
is a very bad one to get into.

There doesn't have to be any. It is easy
to separate psychologically the practice
with a strong program and real playing,
be it with humans or even with a program
but when you play in a competitive mode,
without takebacks.
