I bought a few Dover Books from amazon. They seem to be cheap partly because
they are in descriptive notation, but as I was brought up on that it's not
too much of a problem and they are truly excellent value. At the moment I'm
going through The Art of the Checkmate. Very informative. Anyway, my
question: in one of the games White plays the move
7. KKn-B6ch.
Now that's not too much of a problem as it's in the first 10 moves so I've
still got some vague idea about which is the KKn and which is the QKn, but
what about, say,
83. KKn-B6ch
Am I the only player who doesn't keep track of which Knight is which for 83
moves? I realise there is an alternative notation of say Kn(K4)-B6ch. When
does the KKn become Kn(K4)? What are the conventions?

cheers
