How many ELOs can we >see for real (SSDF)? ;) Well, you need to be precise before making any critic: SSDF is testing Shredder 8 CB and Shredder 7.04 UCI 1. Shredder 8 CB is using CB interface, which slow down the program a little cvompared to UCI and has a different learning feature too 2. The opening book has 2 reading mode in CB version as the tournament one is the std. book selection of UCI gui. This means that a wider range openings/moves are selected in this mode, so moves which are not really strong are played too reducing the strenght by some points. I have said that Shredder 8 CB is the update of Shredder 7.04 CB and Shredder 8 UCI is the update of Shredder 7.04 UCI SSDF did not test Shredder 8 UCI, even if we asked, so it is not my fault if they did not. P.N. I have explained how I did estimate the strenght based on the Classic interface and how much was related to the book and the different learning too. I did also pointed out that they were INDICATIVE estimates as my interest is not to find out how much stronger is a new program/engine as but to make better books for the next outcoming version. As soon as a new version is released I am working on the next one/tournament book version (the future). Who tested Shredder 8 UCI did admit it is stronger than Shredder 8 CB, so I do not see any :-) to be deserved or not? This time however there are not estimate made by me...the fun will be left to you all:-)) Sandro
