I don't have an opinion yet, except that the >above list is written in decreasing probability order.... 05. Interview team: The unbelievable results of your program caused a lot of wild speculations in all chess computer fora. Some spoke of a Crafty clone while others suspected that Ruffian was a Fritz clone. After the release of your program last week the speculations have calmed down and people have stopped looking for such explanations. At least openly. Are you angry, offended or indifferent regarding such allogations (sorry to say but there have been published quite a few clones in the past) from people who cannot understand why Ruffian is so strong? Do you understand the underlying behaviour? Per-Ola Valfridsson (Ruffian): I can understand if some people was suspicious until ruffian was released. If someone compares Ruffian with Fritz, I take that as a compliment
