First of all, it either says KN or KKt, not KKn, right?

Right. My mistake. IIRC it's KN.

Have you actually seen 83.KKt-B6 ch?

Nope. I just used it to illustrate my question.

I would guess that it is only in
situations where it is obvious which is the KN and which is the QN that
you
would see that; you are worrying about a situation that never arises in
practice. And my preferred usage is that, say KN-Q2 or QN-Q2 would only
be
used where one N remains on its starting square or where each N has made
no
more than one move from its starting square. Otherwise it would be
N(K4)-B6
ch.

Sounds good to me.

cheers
