No it isn't.  My argument is "I once mixed chemicals A and B and got this
result...  Someone else also mixed A and B and got the same thing.  Someone
else wrote a paper describing that when they didn't mix A and B, they had a
problem but when they did mix them they got the same thing too." (this last
was GreenBlatt in the Digital Press Journal in the paper describing the
chess program he wrote).

If you don't want to believe me, feel free.  I made a simple statement that
was supported by my results and the results of others.  If you choose to
ignore those results, that is up to you.  Being "Bob Hyatt" has nothing to
do with it.  I _know_ what goes on when this gets screwed up, based on personal
experience in finding/fixing the problem.  Vincent supposedly had the same
problem.  GreenBlatt, Slate/Atkin, Thompson, etc all used the same approach
to solve the problem.

I didn't take it there.
