Hi Michael, > http://chessprogramming.org/cccsearch/ccc.php?art_id=333335 well, I believe that Frank came to that conclusion because of the results he got... okay, might be a bit marketing also. The SSDF-Result anyway does not say that Ruffian 1.0.1 was/is stronger then Ruffian 2.0.0 - look at the margin of error ! Anyway, it seems clear that under the conditions they have tested it, Ruffian 2.0.0 is not as much stronger as Frank thought. On the other hand I do not know how they did test it. Which book was used and the main question: did they use Ruffian as UCI or WB. In UCI-mode booklearning is not working -> for matches like they are played at SSDF booklearning is very important. (By the way, this makes the result of ChessMaster 9000 even more interesting. Even with standard setting, without learning and its own book it achieved a quite good result. Also Eds porting to a Windows-version was definitely a success - he even gained some strength which is not usual, I am thinking about Fritz 3 / 4) Besides, this is no critic to SSDF - their list is still the best we have for long time controls. Greets, Thomas
