Such an imitation, if it's a good one, can be a valuable tool for
looking at my positions and decisions from a different perspective,
and for making my positions and ideas more clear and correct.

My worst enemies don't necessarily bring up only invalid arguments.
When they do, it is my job to detect the invalid arguments and
disregard them.

The art of discerning between truth and fallacies is an important
one.  How do I know that every one of my arguments and assumptions
is valid and isn't based on a fallacy?  Confronting those with the
ones provided by an opponent helps me make this distinction, and find
fallacies in my own opinions and ideas.

I'm not interested in "honesty"; that is almost immaterial.  If the
arguments are good and valid, the honesty of their proponents is
irrelevant.

Opponents and adversaries normally don't want to help me, they want to
convince me that they are right and I'm wrong, or cause me to fail in
achieving my goals.  All I'm interested in is to hear those arguments
and take the useful parts out of them.  And there are always useful
parts, in many cases a lot of them, IME.

> That's totally different from playing devil's advocate.

I will be the one who decides whether it helps me or not.  The intent
of the opponent is not important, only what he/she says is important,
and how I use what he/she says for my purposes.

They need to play the adversary, and do it well.  Whether that
includes "by hook or by crook" depends on the domain; for example, in
Cyber warfare it's entirely expected.  The red team is also supposed
to cast doubt on every single assumption that my decisions or plans
are based on, and ask the "what if" questions that perhaps I didn't
ask myself.

> and cheer if the plan is stopped?

That is entirely irrelevant.  Their job is done when they succeed in
pointing out problematic assumptions and weak points in my decisions
or plans, which cause me to modify the plan, prepare plan B, etc.
