I think I messed up in what I said.  Instead of: "the DB team admitted that
even DB '96 had a somewhat weaker evaluation than the top Micros of the time",
it should have been DT I mentioned.  DB was of course better, and DB2 much
better still.  And I do think the Nolot test can prove something...If you'd
like, I can look up their exact results (I think it's the original email from
Hsu to Pierre Nolot about the test.)  DT was a tactical monster, and much of
this power came from their search.

Thanks, I'll have a look at this.

If some random GM plays a program 1 game on a P-200, there is a significant
chance that he'll lose.  But I think in a match the computer would have no
chance.

Don't worry about offending me - it's very hard to do, especially online. :)  I
definitely respect your side of the argument, but I am simply of the opinion
that DB '97 had better search/evaluation/speed than even the best micros of
today.  If I have any facts supporting that, I will try to present them.  But I
will also be willing to change my mind if some good evidence is available that
suggests I'm wrong.

Jeremiah
