For an uninteresting topic , you posted long reply. It is interesting idea that
you mention this "scintific experiment" belief that you believe Kasparov held
about the match. I attended Game 6 in Phildadelphia in 1996. After the winning
the game and match , he talked at length to the 500_ attendees about his feeling
regarding the games and the match. He repeatedly refer to the match as an
"experiment" and as a science endevaor.
But he would be naive to think that the IBM team was not interested in winning.
Note I refernce the IBM team and not the IBM Corporation. IBM was getting
tremendous corporate PR from these events. They were covered worldwide , their
Deep Blue webpages were getting millions of hits per day during the matches.
They were "winning" whether Deep Blue won or lost. But as soon as Kasparov
accused the IBM team of potentially cheating in the match, that would have
turned the IBM Corporate executives and PR types totally against any further
involement with Kasparov period. The one thing worse than no PR is bad PR. The
accusations were bad PR for IBM and that is what killed any possible rematches.
They had a great thing that could have gone on for years if Kasparov was not so
careless in his unfounded accusations.
Kasparov himself crushed the golden egg that was there for him but as you out
put it, he was mentally psyched out by DB that he played very un-Kasparov like
and certainly was not his best form. I also think that him pacticing against a
Fritz 5 ( maybe a 150 Mhz Pentrium) wa the absolutly the worse thing for him to
do to prepare for the match. To me, from a distance, it looked like he
developed pet strategies (unorthodox openings, closed games, etc) against Fritz
that he then tried to apply to Deep Blue. But Deep Blue was not Fritz 5, they
were light years apart.
Even now, when one looks at Game 2 of the second match - the first alledge
suspect move was 36. axb5. The natural move here is Ob6. Most programs show
that Qb6 is the best move. Deep Blue played axb5 - a much better move in my
opinion than Qb6. Deep Blue logs show that Ob6 failed low and then went into
panic mode (allowing for extra time on the move) to come up with axb5.
I amo now running this position on a Dual Opteron with Crafty 19.20. It is
still running and after 8 hours , this is what we have:

One can see that Ob6 is not only falling, the pv is showing many checks by
black's queen that appear to be a great nuisance to white's game. I will let
this for w a while longer to see if Crafty finally moves off a Qb6. Right now,
axb5 shows up as Crafty's next move.
