Depends.
A race car that won an important race is up for sale. It is advertised as the
same race car that won that race. Everything is there, down to the tires.
However, the special racing oil used to improve lubrication and that also helped
improve its performance is not there. Is it false advertising?

How is this relevant? I see the _engine_ as being the World Championship
program. Even if the GUI used at Paderborn were completely different from the
commercial package, and I believe it IS different from the commercial package
though only Stefan could say, I would still agree that I had gotten the WC
Shredder. So if you stand by the argument that Shredder isn't really Shredder
without the tablebases, then we'll just have to agree to disagree here.

Of course they should give him every courtesy, but the question isn't on what
Kasparov could have gained by seeing the printouts. The question is _why_ he
asked for the printouts in the first place. As far as I'm concerned, that's the
starting point of it all. You see, my theory starts and evolves a little
differently. Kasparov asks for the printouts. Privately (I recall nothing being
said about Kasparov asking for them publicly, but rather on his accusations that
something was amiss, which would be after of course). The Deep Blue team is
confounded. Why does he want the printouts? He never asked for them in the first
match, nor did he request them either before or after the first game, so why
now? Furthermore, the printouts will certainly reveal _much_ to GK just by
allowing him to see what the computer thinks of key positions and the analysis
that led it to those evaluations. That's quite a lot. Naturally they ask him. GK
may beat around the bush a little, but eventually he will have to tell them. I
don't believe they would have swallowed a cute little speech about scientific
truth by him. Not there and then, in a match with a million-dollar prizefund.
This may be coffee change for IBM, but it isn't for GK, and there is no reason
to just hand the match to him. So he tells them. He doesn't even have to be
rude. Let us imagine he is as tactful as possible under the circumstances: he
can't believe a computer could play some of the moves it did. Only a human could
play such moves. And lest you say that GK would never say such a thing, I'd
suggest reading the interview he gave to Playboy magazine some years back. His
opinions on what women could or could not do were straight from the Stone Age.
In any case, it may have been eloquent but it is still an accusation of
cheating. If you have a different theory on why he asked or what he would say to
justify it, please say, but remember that he stood by his accusations in public.
I never heard any denials from him.

So there it is. The world champion wants to see the printouts to make sure no
cheating is going on. How would you have reacted? Do you believe that courtesy
should also go that far? So the request is heard by the DB marketing team from
IBM (I doubt Hsu was empowered to make that sort of decision). They basically
are being asked to give up vital information in the beginning of the match in
order to satisfy GK that they aren't cheaters. Frankly, I would not have given
them to him, world champion be damned.

In the US, there is a constitutional right under the 4th amendment that protects
a citizen against unlawful searches. If an officer of the law were to ask you to
turn out your pockets in order to be certain you didn't have any drugs or
weapons, it is your right to refuse to do so. That request only becomes an order
if the officer can prove he had probable cause (other than having an overactive
imagination), otherwise they are the ones breaking the law.

For the public record, IBM did release the printouts on the key positions after
the match was over. Yes, they could have been doctored or plain made-up, but
there is no evidence to support this.

I don't believe that's true.

I did and I don't see them as arguments. Yes, they could have cheated. Easily.
So what? I see no reason to presume they did. Is there any evidence whatsoever
to support such a belief?

I would have had Hsu, or anyone involved, commited to an asylum if I had
witnessed such a speech.

Yes.

How was this conclusion reached?

I have yet to see how Hsu was to blame. Furthermore, the statements issued gave
conflicting versions of what had happened. On the one side we have Hsu making a
direct appeal to Kasparov and stating that this was done in the most civilized
manner, and on the other we have GK's manager declare that Hsu's letters had
been hostile and belligerent. Unless the letters are published, we'll never
know. It could also have been a result of a less than perfect English on Hsu's
part. Still, the declaration didn't state this as the reason for ending the
discussion, but that the DB chip and its rights that were now in Hsu's sole
possession was not the DB that had beaten GK at all. An identical circumstance
to the Shredder episode now appears: is Deep Blue the chip and its creator, or
is it the company and the computer that housed the chips?

I don't agree.
