Hi, I'm also a computer programmer.  I have made an amateur chess program,
Pluto.
I think what you say is possible. I just never have seen this done or have done
it myself (!)  It's easy to describe pieces and pawns in chess--computers and
humans do it all the time.  e.i. king is weak, bishop is bad, knight is strong
on outpost, piece attacks weak pawn...  The key is to start out with something
simple that works consistently, and then add on to that and test it.  One might
end up with something quite advanced after some period.  I don't deny that that
there may be several problems due to the algorithms used in chess search.  On
the other hand, there may be workarounds.  The program should be able to avoid
giving stupid explanations because it gives high quality lines.

It's true, pure analysis output is not always desirable.  There is a reason
behind every move.  When I play a computer, I have situations: 1. I want to know
the best move and why it is good 2. I want to know why the move I am about to
play is good or bad, and I want to know why it is good or bad 3.  I want the
same for any moves I have questions about.  The why part would preferably be
answered by explanation + concrete variations.  It's a pain reading off and
visualizing/playing pure lines on the board.  It takes the focus off the
abstraction element of chess.  This is of course not true if pure analysis is
what you want.  I'm sure pros would be more focused on the lines than a
computer's explanation.  However, the explanations would be convenient,
friendly, and interesting for the average and lower players.

I'd be interested if somebody could give me reasons why it's not feasible--but
try to come up with workarounds.

Michael
