I might be naive but in the light of your informative answer the meaning of my
question possibly was what could be the incentive to tune your program on such a
shallow basis. Because the possibility is clear that the others in their team
might also not sleep and perhaps had presented you a red herring only to go for
another tune without you're being aware of. In short. Is it really the most
important thing to do such book cooking, or is it more important to find new
code for the improving of your baby??

For me as a layman it looks strange that shortly after Ed published the prog
Thorsten tried to improve it. Or is it because he hopes to become the next
operator of Rebel? Or ist just, as he said, a nice pass-time.

But how could you define it as flame war??? I thought I had discovered something
interesting. Believe it or not. And didn't you know that it isn't a good
argument to rely on the status of someone without going into the details? If you
teach me this way then why did you make that flame war against Bob Hyatt? I
could ask you in the same style.

Please tell me more. Incredible. I did never read something about it. How can
you conclude that certain testers left out lost games? Unbelievable. If that is
true.

Thanks for all these interesting news.

May I ask your opinion for one further question? Could I believe for sure thast
the last tournament version is always the next public version??? When I think of
Shredder, it gives me the idea that Stefan MM has something in his tournament
machine he would never sell in public versions! Am I right with that guess?
