Eduard is now changing sides again from at first seeking for the basic model for Ruffian and now he's in its defense against a dark conspiracy by the established interests. Of course, Ruffian could still be some, say Dark Thought clone. The idea that someone came out of nowhere and could all on his own, without book cooker, make a program stronger than Fritz, this is impossible. But above that possibility there are many reasons why Ruffian could be a new program by some people who have understood all of the actual computer chess techno. If Thorsten alone could already make Rebel many points stronger then a team should be capable to do such things. Understood that they got a basic motor they could work on. From the time aspects I see no lonely single programmer who could possibly do that. Even less probable if he had not the present of a good motor. So why shouldn't that be possible? I think it is. But the whole secrecy in the past weeks is a bit strange. Some people seem to be interested in the proof that a totally new prog could be better than the commercially established progs. But up to now I agree with you, the proof is not there. But it could succeed. But also that was not the question. The point was if one single programmer could come up with engine, book and all only on his own. Improbable was the verdict here. And that has not been rejected since. Rolf Tueschen
