I do not agree. They were good against other computers, not against Kasparov.
This is my believe.

I know it.

Yes, it is the weakest point, but he is a human so he has some weak points even
if relatively weak.

This could be a weak point...don't you think so?

Did I said so?

Nearly never...not never...

Golia had no chance theorically, but it did won David...nothing is
impossible...it is however quite difficult...this is the difference...

Yes, they used to have very many...now not that many...still a lot...

Believe it or not I earn much much less?

Do you believe it?:-)

Hydra cannot win...at least not in the next at least 3 years...my
opinion...things are changing it is difficult to make too long time
statements...

OK, you know my opinion of the match...

Yes, this is true, but still the gap was impressive...to me...

I believe that he wanted a draw score to make more money with more matches in
the future...after the disappointment from IBM...he learns from experience like
everybody else...:-)
