Please quote where I denied that.  I didn't deny _either_ result...

I have no idea what you are talking about.  The DTS test and my dissertation
tests were wildly different.  One had 24 unrelated positions, searched to fixed
depth, on very slow hardware.  One had 24 consecutive positions from the same
game, searched to variable depth, on very fast hardware...

And I didn't "fraud" any numbers whatsover.  That is your word.  But you are the
fraud expert of course...  being the biggest fraud here by orders of magnitude.

So do I.  Different test.  Run a different way.  With pre-loaded hash tables
carried across moves.  Etc...  BTW the difference is 20%.  Of course that is
"substantial" in your small world.  Even knowing the two tests were not intended
to be compatible.  My dissertation did the same test everyone previous to that
had done, the BK positions.  The DTS article tried to answer a _different_
question, but apparently that subtle difference is lost to your "great"
intellect...

Do you remember anything I have written about this?  About the fact that old CB
executables exist in old Cray users group libraries?  There used to be plenty of
executables to be found.  There may still be executables around if you look hard
enough.  But no source.

So do I although again you blew the wording...  What you claim I wrote I _never_
wrote.  But that is nothing new is it???  But as far as that match goes, it was
interesting.  It was made possible by a friend (who shall remain nameless)
calling and saying "we are shutting our C90 down today.  But it won't be moved
until the weekend.  Want to try a demo or something as I have an old copy of CB
running on it that I use to test against my program..."

So I ran for a while, until it became obvious that it was not going to be very
interesting.    I'd bet the quad opteron would have come out ahead.  But not the
quad xeon I had when I played the match...

But what does this have to do with anything???
