Wishful thinking. Now, this is the proof for the total end of traditional
computerchess. You stopped the main discussion about these ethical questions in
the debate with me and you come here (into a debate with someone who never was
in the debate, at least not with his name) to "declare" the whole question as
"pointless". Excuse me if I say that this isn't sound. For me it's completely
unbelievable that you can't understand the consequences of your own statement
(the principal unsuitability of the logs for for proofs and validity). At least
the logs of DB2. You completely miss the consequence that your friends, the DB2
team would've had the duty to design a water-tight and well documented output.
That is the bad side of the simple questions of Kasparov. And _you_ could give
us no answer.

As I said already Kasparov didn't mean what you are trying to imply. But even if
he did mean it it won't help you and your friends in the DB2 team for the
question of their behavior during the event in 1997. Not to speak of the
deconstruction!

You know very good that your experiment is not a proof against Kasparov. Your
experiment does not answer the question why CC and the DB2 teamm as well never
discussed the question of a safe output. The sole purpose is to create alien war
fields to prevent that many people finally understand what is wrong in the
tradition of CC. Why don't you support the reformation of traditional CC? What
is the reason why you support false methods?

This is not true! All we could state is that traditional CC did never search for
such security measures. In the past for understandable reasons but after DB2 in
1997 and Kasparov's questions we have a new situation.

And the necessary ingrediants had been implemented... ;-)

For good reasons of a non-question of honesty, but this has changed after DB2
team in 1997, Bob. GM no longer believe in mutual respect. They want control of
the whole matter. Look how Kramnik proceeds with FRITZ (not joking!). :)

I have general questions for you. Why do you think it preferable that the whole
question must be confused? Why can't we discuss ethical questions? Why the
methods of the old days must be good methods for these days too? Are these
methods, or their philosophy connected with economical importance? Why something
bad or unsuitable must be presented as undisputably the sole solution? Can't you
see the desaster such hopeless deadend tries will spoil the thought processes of
our young computerchess experts? Questions to think about.
