I have no reason whatsoever to help John J. in
particular improve his comprehension of chess.

A friend (who's rated 2100+ in correspondence chess)
of mine often has asked me (he regards me as a much
stronger player) for my advice and analysis about chess.
And I have given freely of it. If he were a stranger, however,
then I would expect some compensation for my time.
