Deep blue was mostly based on raw comremovedtional power, with very little ability to actually judge whether a draw was “good” without calculating the possibilities following it.
As I understand it, it only worked on Chess as a “mathematical” problem, and was incapable of judging strategic positions, except if it had “seen” it before, and already calculated the possible outcomes.
In short, there was very little intelligence, it was based only on memory and massive calculation power. Which indeed are aspects of intelligence, but only on a very low level.
