I'm watching engine-engine-games. I did not watch games of Crafty versions but saying that Crafty17.14 is clearly better than later crafty seems to me an insult to Bob who continue to work on crafty. There can be a small difference but I do not believe that a big negative difference can happen when Bob does not find it. In order to be convinced in small negative difference you need hundreds and maybe thousands of games. I know that Bob add knowledge to Crafty so I simply cannot believe that it is significantly worse. A big bug can happen in a version but I do not believe that it can stay for a lot of time without correction so big bugs in Crafty1715 were probably fixed later. >I see when an engine-creator would to have give up his previous good >selfestimastion. (Does the author of "Genesis" still tells at his hp his engine >is ~22oo Elo...?). I think that the rating of programs is dependent on the hardware and the time control and the question if the human opponents are prepared to play anti computer. I believe that genesis can achieve 2200 in the right conditions. > >Watching several games, I know if an an engine-version became better or not. > >You said that "you do not know it", but saying "there is not big >difference...". > >Contradictio in adjecto? No I know based on rating lists that there is a no big difference. I do not know which version is better. > >Or did you mean that Crafty1714 is unknown to you? I may look at numbers again(I remember that Sarah has lot of Crafty in her rating list but I do not remember now if 1714 is one of them. I am going to look for her posts in the last week and find it in a few minutes. > >Best regards and wish of peace to Israel, I also hope for peace. Uri
