This is not what hyatt said. Hyatt talked about the same program and Hyatt also did not talk about law levels of 2000. I believe that Hyatt may be right that the +60 is translated to +30 or less than it only if the humans learn the machine and try to play anti computer chess. Practically it almost never happens in tournament and the proof is the fact that I remember nobody who tried to play the trojan horse sacrifice against machines when they played against humans in tournaments. nemeth did it in games that he posted and humans could also do it some years ago against old hardware. I suspect that if humans learn to play against machines seriously the programs with ssdf rating of 2000 may get less than 1600. Uri
