Testing of Chess Tiger 2004 Normal is limted in that only a couple of CEGT testers have it. It was agreed to run 80 games per engine match however there was a mistake regarding Ktulu 7.1. Testing of Chess Tiger 2004 Normal is also limited in that it only runs in the Chess Partner interface and therefore the variety of engines to play against isn't so great. Further the method of testing within Chess Partner don't allow easy use of match play gauntlets as Chessbase GUI's do. Last assuming it will end up playing some 1500 games ultimately it's rating may get a bit skewed at the beginning. Sarah.
