That plugs several more holes. We do not know if it was a different animal because kasparov did not try h5 and he had the opportunity to try in game 2. I also doubt if GM's tried the idea of 1.e4 e5 2.Nf3 Nc6 3.Bb5 a6 4.Ba4 h5 against deeper blue. I doubt if tuning the evaluation based on games against humans could help because there is a lot of things that humans did not try. I also found that Deep Fritz could avoid the drawing mistake of Deeper blue in game 2 and the same for Junior and Tiger so claims that the evaluation of Deeper blue was different do not convince me. The fact that the evaluation of Deeper blue was different does not say that it was better and it is possible that it even could fall for king attack that Deep Fritz does not fall into if you play the relevant lines that kasparov did not know. We have no idea if kasparov could win Deeper blue in game 2 by h5 for the simple reason that kasparov did not try and everything is going to be a speculation. Uri
