I seriously doubt that it is true that we all know that. Nimzo 8 simply seems to have less fans ; the Nimzo results posted look very promising at tournament time controls. >I just finished a small test in which Fritz 6a using Nimzo 8.ctg or Opening book >beat Chess Tiger 13.0 8 games out of 15 at G/30.

This might have been a bad test for the question discussed as both books ( Fritz and Nimzo ) were prepared by the same author : Alex Kure. A good test might be to use the general.ctg of Fritz 5.32, Fritz 5 or Hiarcs.ctg if you have one of those which were (or are said to be) automatically generated books made out of grandmaster games . So then you could pair Fritz with one of these books against Tiger and then compair to the result with the Fritz6-book or the nimzo.ctg . For test purposes it would be best if you could turn off book learning for the competitors but as I don't know how to do that with the Tiger book it might be best to just leave the learning as it is ( which probably will show the effect a little less clearly ) . You would have to play a huge number of games to get a reliable result if the ELO difference were about 30-50 points it seems you would have to play at least about 100 games with each constellation to see this trend . I don't want to convince you to do these time-consuming tests I just think I'd like to see the results if someone did it . Another good comparison would be Crafty with its own book against Crafty with one of the Kure books btw ; I suspect the trend would be much clearer here. greetings. pete > >Pichard. >> > >>Nimzo is known for its strong book, however all the books you mentioned are made >>highly skilled individuals.
