There are more SMP commercial engines than there are non-SMP >commercial engines... I am not so sure about that. Are there any commercial SMP engines except those you mention above? I could easily mention much more than four commercial engines which do not yet have SMP support. And even though several commercial SMP engines exist, I doubt that their authors have spent anywhere near as much effort on parallel code as you have done. How well do you think they scale beyond 2 or 4 processors? >Also care to make a bet about +5 years from now as to whether your statement >will be true?

But everybody don't have the same goals and interests for the future as you. To me, chess programming on desktop computers is beggining to get less interesting already today, because those computers are already so damn fast. It is no longer a very difficult task to create a PC program which beats 99.99% of all chess players. Further improvement has mainly academic interest, except for a tiny group of elite players. I consider it a much more interesting challenge to make an engine that plays well even on small handheld computers and mobile phones. Not only is it more difficult to make a good engine with limited memory and a slow processor, handheld devices are also a much more pleasant platform for playing chess. Tord
