Hi Joachim,

thanks. Just a few points concerning critics.

Ponder on and own books or general book or Nunn/Noomen positions are things
where we have a lot of experienced testers with different opinions. The
advantages and disadvantages are known and I do not repeat them here.

Different namens for engines: Well from all databases I am getting daily I give
downloads and sometimes I am to lazy to rename something like Ruffian 2.10 to
Ruffian 2.1.0, etc. In the big database for rating calculation I am having,
those are of course given one unified name, here Ruffian 2.1.0

Shredder 9 native engine and Shredder 9 UCI we are mixing as testers have
different ones. We could not detect differences in speed here. Ktulu 7.0a is
only a bugfix for Ktulu 7.0 and seemingly does not affect playing strength, so
the versions are combined.

Time controls: adapted via Crafty benchmark to 2 Ghz P4 CPU, admittedly not the
fsstest, but you will see many tournaments with slower hardware, so it is still
more or less standard. With technical progress and more testers we should adapt
time controls to faster hardware. For the moment those with faster Athlon64 are
enjoying that they only have to give 40/18 repeated.

Different time controls in headers: there were a few tournaments in AEGT Bishop
and Knight Class where we experimented with a time control 30 minutes + 15
seconds to avoid this longlasting games with repeated time controls (we often
have games with 150 moves and more). But when we saw that engines had problems
with this, we voted to cling to the x moves in y repeated.

Fritz GUI: hated by some Winboard fans and other people. Buggy for many years.
Problems are fixed with newer UCI.dll, also the 1MB bug. Believe it or not this
GUI is not worse than others and we can´t run engines like Hiarcs, Chess Tiger,
Junior, Fritz and Anaconda in other GUI´s. Whenever it is possible we have still
some Arena fans who are more acquainted with that one.

Every tournament, even SSDF has weaknesses, the perfect tournament will never
exist. Anyway testing in groups is fun, there is a lot of advice and help from
others and interesting exchange of opinions.

Best Regards
Heinz
