I have always said it was an opinion.  I have always said that "deep thought
proved itself against micros".  It did.

However, "opinion" about DB does have some basis in fact.  An example:

I race boats here regularly.  A friend of mine has a good motor on an
Allison hull.  I know how much the Allison hull weighs (800 pounds) and
I know how much horsepower his merc pro-max 225 puts out (225+).

A friend of mine asked me what I thought this hull would do with a merc
high-performance 2.5 EFI motor on the transom.  Knowing that the 2.5 is
rated at 265 horsepower, and that it makes closer to 300, I speculated that
it would be _significantly_ faster than the pro-max 225 version.  Based only
on logical reasoning:  same weight, more horsepower == more speed.

With Deep Blue, Hsu did everything he did in deep thought, but he did it a lot
faster, he added even more eval, fixed some known problems in DTs hardware (no
repetition detection in hardware, etc.)  I don't consider it a "guess" when I
say that DB is obviously better than DT.  And then Hsu played games between the
two as well, with Joel evaluating how it was doing.  It significantly outplayed
DT, and then DB2 outplayed DB1.

Is that just whistling in the wind, or is it sound reasoning?  IE I _know_ that
Crafty on a 16 cpu alpha is stronger than Crafty on a quad xeon.  But that is
_still_ opinion since I haven't had a chance to run a real test.  But intuition
can't be wrong here...
