Hello, looking through all the postings here I guess its time to say something about the intention of the ELO rating list at http://www.schachcomputer.info. 1. We decided to test only stand alome chess computers and not against PC programs (this is done in the SSDF). We think there is the mismatch between the (by 100 points lowered) SSDF results and the real strength of the chess computers, which was introduced in the SSDF more or less due to the big gab between the PC programs and the "old machines". We did not make any restriction regarding whether or not a chess computer is commercially available or not. Even tuned machines of the same program are welcome just to study the influence of the speed on the program strength. Therefore we also added the V11, knowing that in the meanwhile quite a lot machines are existing (maybe more than R40s!) and we were able to collect more than 200 tournament (!) games in less than 1 year! Of course one can discuss whether or not the chess machines shouls show up, but as at least the CM at 14 MHz are absolutely identical to the Mephisto RISC modules we decided to merge them. Therefore we also took the 32 MHz CM in the list. 2. Regarding the opponents of the Ruffian program I agree that the selection is very small so far, but I guess its a starting point. Please do not forget that there is a huge statistcal error. In addition to that, we have to rely on the contributions from all the (rare) chess friends who are a proud owner of Ruuds machine. As you know there are only 25 machines and I guess to my best knowledge only up to 6 guys are playing with it (Many thanks to them all!!)! I tried to match the Ruffian program against the strongest programs I have, but not everybody owns a R40 or Turniermachines :-(. We also thought about matches via internet on the chessgate server but this is even more time consuming and more difficult to organize than playing at home at least if you think about a statistically relevant match of 10 or 20 games. 3. We have currently started of course playing with the Resurrection Fruit '05, 17 games are available, enough for beeing accepted in our list (minimum is 16 games against at least 2 opponents). It is alreday clear that it is much stronger than the Ruffian 2.1. Maybe we will be able to present a small update of our tournament list before the end of the year. But again there will be most likely no game against the R40 as long as the machine from Hans van Mierlo is not succesfully being repaired. best regards Stefan
