Subject: Computer Endgame Advise Requested

Author: Stephen Ham

Dear Computer Chess experts,

I know that many of you are following my 4-game Human versus Computer
correspondence chess match versus Fritz 6a and Nimzo 7.32, carried at:

http://www.correspondencechess.com/campbell

Since I am ignorant of computer chess, I need your advice on how to deal with
the following issue.

Fritz 6a-Ham has reached a clearly drawn endgame. However, becuase of the
material disparity, Fritz 6a belives it is winning by 2.69 pawns! We have
installed the 5-piece endgame table-bases, but it is clear that neither side
will liquidate from our present 6-piece ending into a 5-piece ending, which
would prove the draw to Fritz 6a. The problem is that I don't want to play out a
drawn endgame "ad infinitum" just because Fritz 6a thinks it is winning. If we
instead stop the game and have someone adjudicate it as a draw, then weak chess
players are going to scream that we "fixed" the result to favor the human (me)
when the machine showed it was winning and had a material advantage.

Does anyone see a reasonable solution? Your input is appreciated.

As a side note, I've been asked by several interested parties to put together an
even more in-depth commentary than I already have (is such a thing possible?) so
that it could be sold as a book. I've thus planned to do a "post-mortem"
analysis togther with the chess-engines where the chess engines will check my
analysis and I theirs, just to keep the analysis as correct as possible. Other
than this, what would you readers like to see in a revised presentation? Thank
you in advance.

All the best,

Stephen Ham
