Then Ferret should be blown out by CST, too, and this didn't happen when Chris
showed up with it on ICC.

But in any case, I don't think Ferret is similar to Fritz.  My understanding of
Fritz is that it is a root-evaluator using null-move and possibly some other
aggressive pruning.  Maybe Fritz 5 is different, I do not know.

Ferret uses null move, sure, and a little razoring, but no rocket-science
pruning.  It evaluates at the tips, and it does a lot of stuff that you probably
don't think Fritz does.

This can describe any number of programs that you wouldn't regard as being
similar to Fritz, I think.  Do you think that Crafty is similar to Fritz?
Ferret is pretty similar to Crafty, because Bob and I talk a lot.

I see it killing things on the net.

I think that part of the problem here is that you say things, then apparently
forget that you say them.

Right. The autoplayer cheats. The people involved have nothing to do
with the cheating. They are only OWNERS of machines. THEY do not produce
the data, they are only OWNERS of machines.
You try to suggest that I call Enrique or you cheaters.
In fact I do call ChessBase and their autoplayer the main problem.

If you want to show something use the Chrilly Donninger auto232-device.
In the moment you use the ChessBase autoplayer you cheat.
Do you get this right ?!

-----------------------------------------------------------

End of quote.  You also made some more ambiguous references to the autoplayer
cheating in 16403.txt and 16454.txt (In this one you said either the autoplayer
was cheating or Moritz was cheating, but that you weren't going to sort it out).
 This was all in March and April.  I didn't look past 16486 because that post
seemed to be pretty clear.

In any case, I don't particularly care, other than that you made me doubt my own
memory.  My statement was that *I* don't think that the autoplayer cheats.
