My point is that two things are happening here...  1.  some GM players have a
lot of disdain for computers, having been exposed to micros and finding them
relatively unintelligent, excepting for fast time controls.  And they assume
that *they* can analyze more deeply and more accurately.  (more on this in a
minute).  2.  these same players look at some positions and say "white is
winning..." and that's that.  Care to look thru a good opening book and let's
do the following:  I can pick *any* opening where the analysis is +- and you
have to play the white side of it, with a wager of $10,000 on the outcome.
You know what would happen there, correct?  Because there are lots of such
annotated games where something *serious* was overlooked, and instead of being
+- it should be -+.

The thing that most bothers me about the comments about game two of the DB
match is that *everyone* agreed that the computer should have played Qb6 and
won a pawn, with a probable win as the result.  And they all agreed that a
very strong human might have tried Be4 instead.  And *all* overlooked that
Qb6 leads to a draw.

So what is convincing when they say that in game X, DB was lost, but it managed
to swindle a draw because Kasparov made a mistake.  Perhaps it was the other
way around.  The game was a draw due to some deep but unseen tactics, and
kasparov played perfectly to avoid letting it turn into a loss.

I've been around too many computer chess matches.  20 years ago the masters and
IM's were pointing out mistakes here and there in every game.  10 years ago
they were pointing out mistakes and occasionally finding they were wrong.  At
the last few computer events I attended, when the computer would make what
appeared to be a blunder, the IM/GM players would start trying to figure out
what was going on, assuming that the move wasn't a blunder but was actually
forced.  A 180 degree turnaround in thought process, because the computers were
suddenly right way more than they were wrong.

I've seen nothing to convince me that this couldn't have happened in the games
that DB drew...  ie they were drawn all along, rather than being won by Kasparov
until he made a fatal blunder (or blunders) in each...

So just because a GM publishes analysis that says that this game should have
been won, is *not* convincing.  IE check out the comments by GM Shirov.  He
published some positions that he claimed would take days, weeks or months
for a computer to find... and Crafty found most of them inside a tournament
time control.  Given that level of misunderstanding, how badly do you think
they might be underestimating Deep Blue, which *really* understands tactics?

That's part of being a scientist.  I believe what I can prove.  I try to
prove what I want to believe.  And proving means producing some real data
or results...  ie playing the game.

The most common statement I heard after game 6 was the famous "any micro
program could have won game 6, after Kasparov allowed Nxe6."  We now know
that this not only was wrong, it was grossly.  Several have tried this from
the white side and no micro has been able to win yet.  So I accept this as
proof that the earlier statements were wrong.  Ie it would be fun to play
a couple of GM players starting from that position and giving them white, just
to see if they can produce what they say they can...
