I disagree.DeepBlue would get slaughtered ;by todays top commercial programs.
It is known that standards in the midninties were not very high compared to
today.I think you over estimate Nodes per second for some reason.For instance
chess Tiger on Palm has a respectable SSDF rating of 2101 searching about
only 200 positions per second on the palm.A decade ago at such low NPS it was
inconceivable to get such rating.
