Subject: different performance from Fruit against amateurs up to now?

Hi all,

as Fruit 2.1 is currently performing a bit weaker against amateur engines (where
more matches are played just now), there will be an inveetigation by the CEGT
group afterwards if generally the rating performance for top engines drops when
being paired against amateurs (in the range of -250 ELO) compared to those
matches against top engines. Just an example: a win against Amyan 1.59.7 would
give Fruit at this point 0.3 ELO, a loss would cost 1.4 ELO.

This investigation will be based then on more than 2000 games each for Fruit and
the top commercials, as we are intending to play this amount and will not be
content with the error bars of +-20 ELO after 1000 games only. So all matches
will go over 50 games, the complete CEGT rating list up and down.

Fruit 2.01 is currently the number three of the CEGT rating list ranked between
Fritz 8 Bilbao and Junior 9.003. Tomorrow there will be more games against the
top commercials.
