CSTal participated at the championship in Paris.
CSTal participated at the championship in Paderborn.
It participates in a tournament by joern gronemann, on k6-2 hardware.
It participates in my tournament, on k6-3. Before it was in another
tournament of mine, on k6-200 Mhz.
It also once participated in a tournament of Mr. Wiesenecker, but he
used as far as i know a style that was shit.
Also in one of the chlodra/thuringen/aufsess tournaments it participated,
on a cyrix cpu.

IMO it failed to play good at mr.wieseneckers tournament (wrong style), it did
not so good in aufsess (cyrix is to slow), in paris it was ok, also in
paderborn. but in paderborn and paris the playing strength was
disturbed by strange bugs, e.g. lost a won game shortly before mate
because it underpromoted in a knight .-)
but in paderborn it beated e.g. genius, in paris it made a draw vs. dark thought
(dark thought running on very fast cooled alpha machines).

so it is no loser at all IMO.
it all depends on the why!
i guess it the same with other programs.
when there is a big bug in your program, you cannot really count
the games for playing strength. but uninformed people DO count those games
too.
or when you run the program on slow or broken hardware , you get less good
chances (see when junior upgraded it's machine in paris...)...
