I didn't follow every article on the relevant threads, but I thought
the intention was to show your knowledge about the game of chess.  I
thought the discussion was about whether GM Benjamin's article about
Fischer's playing ability was accurate and unbiased.  I don't believe
I have the chess abilities to find inaccuracies in Benjamin's
analysis, so I can't judge whether his article was biased or unbiased.

In my opinion, if another person cannot find inaccuracies or errors of
omission in Benjamin's analysis, then I think that person should not
claim that the article was biased (or unbiased.)  So if I didn't even
know how the pieces moved, I would hardly be fitting to judge a GM's
analysis.

I'm not sure why Bruce would have to be involved in this challenge.  I
thought the match was supposed to be against you and me.  My offer was
to play a three-game match, and the winner will post the games here
with accompanying analysis, annotations, etc.  The games can be
critiqued by the rest of the world, so that we can all discuss chess.

I think Bruce has put you in his kill file, or has made a New Year's
resolution to not follow-up to your posts.  If I were him, I wouldn't
wager on a Class B player.  Heck, I surely wouldn't wager my own hair
on my chess ability.  :-)

** Obligatory chess discussion begins *

After re-reading my post, I'm sorry if I may have mislead some people
with the above paragraph about computers being weak at postal chess.

Obviously, a chess program will be stronger if more time is given for
it to search and evaluate more positions.  This fact is cited in
various literature and is often mis-interprented when people read the
(in)famous Scientific American (Oct 1990) article on Deep Thought II.
That article said something like: given the data collected *in the
past*, the playing strength of a computer has been shown to increase
linearly when the depth of its searching has increased.  It postulates
that *if the trend continues*, theoretically, Deep Thought II could
have a rating of 3400.  But the article makes *no claim* that the
increase in rating will continue to grow linearly with the increased
speed.  My opinion is that the growth rate has to tail off sooner or
later.

Back to my original statement: what I meant to say was that computers
are at the greatest *disadvantage* when playing humans at postal chess
time limits.  The computers will continue to get stronger if given
more time, but the humans can make better use of the extra time, so
the gap between the human and the computer becomes greater in the
human's favor.  I have no specific cited material to back this up, but
it is generally accepted among the computer chess community.

The Valvo vs. DT match I was referring to is in Chess Life (Oct 1990,
Nov 1990).  Valvo won 2-0, so it wasn't as impressive as I thought it
was.  Valvo is an IM and his USCF rating was 2400+ at that time.  I
don't know what DT's rating was at the time, but I think it's
currently around 2500+.

There are several instances of this phenomonon.  I think that Robert
Hyatt, of Cray Blitz fame, has posted here that Cray Blitz plays its
best at speed chess, defeating several GMs.  If you looked at all the
games that machines have won over IMs and GMs, you'll find that the
faster the time limit, the more likely the machine will win.
Furthermore, a group of Usenet users (whose average rating was under
2200) beat MChess, and the 2nd game is still in progress (check MChess
vs. Users).  DT evaluates 100,000s of position per *second*, and
Kasparov still trounced it at regular tournaments time limits.

Computers are very strong, but the average person overestimates its
actual strength.

In my opinion, "a win is a win" philosophy only applies to sports and
other trivial games. :-) Chess is a combination of science, sport, and
art.  Reducing chess to wins and losses would be reducing it to "99%
mathematics".  And how would someone learn from their own mistakes if
they don't have someone point them out to them?

Besides, if someone analyzed a game, then another can better judge the
abilities of the analyzer.  For example, I can claim that a move I
made was extremely strong, but then someone can point out that it was
a blunder because I left my Queen unprotected.  I would have to either
agree that it was a blunder or try to convince him that it was really
a sacrifice (yeah, that's the ticket).

I'm not quite convinced that a GM's analysis must be flawed because he
is human, and how that would translates into bias.  If a GM's analysis
if flawed, how can I prove it?  I don't even have the chess abilities
to find any inaccuracies or omissions in his analysis.  Is Einstein's
notion of physics flawed because he is human?  If they were flawed,
how can I show it?

But we are beginning to digress. :-)

So, DMC, are we going to play a three-game match?  The winner gets to
post the games with accompanying analysis for everyone to scrutinize.
I guess the loser can get to post counter-analysis, or try to show
that the analysis is biased or unbiased. :-)
