The question was for the relation between such entities. Of course you give an
example out of your own experience, but I wanted just know two names and then
the probably same relation than between DB2 and JUNIOR X.

What I didn't understand during the Bahrain hype. Why these guys pretend that
their "new" programming intelligence could equalize, no, beat the velocity of
DB2. That is completely irrational in my mind. Could you explain that? Also
about the Friedel wording that DB2 was faster but did also a huge amount of
redundance with the many processors...

Would you say that your experiment with GENIUS 2 reflects the similar relation
as in DB2 and JUNIOR? Because then the result would be 6-0.

Ah, another question. Would you think that that what they did in the eval would
pay in comp vs comp or more in comp vs human? If possible please give us a few
general factors of importance in that sense of comparison. What is where
especially important. Hope that is not a repetition. I find the explanations
with side looks to the past extremely valuable. What I hope for my questions
too.
