so baron is also clearly worse then ant?
Ant only scored 1 point vs Djenghis and a very lucky half point vs ZZZZZ.

Their opening choice was 'fine' as far as I could tell. Hans Secelle (operator
Ant) mentioned he checked all booklines with fritz and didn't find any
weaknesses. Their search however had some major instabilities. They outsearched
Celes by 6-7 ply on some moves with a too small branching factor.

Also, after 15...Qa7 their position went downhill (Qd5, Qc5 or Qd7 seems better.
Celes expected Wc5, b4, Qd5 IIRC), Celes had a constant +2.xx after 18.Qg3 while
Ant's score fluctuated between -1.00 and -3.00 every couple of moves.

Their major problem seemed to be testing new settings, which 'might' be caused
by people not playing with ancient winboard versions. The programmer of Ant was
already attempting to figure out what caused the search inconsitencies during
the game. He'll quite probably show up with a much stronger playing version of
Ant next weekend, at least, I hope so for him.

Perhaps you should participate in a tournament yourself to figure out the
importance of good books, well tested engines and why to use unreleased
