You seem to be saying based on one position again that a program can not be knowledge based if it does not understand this one position. What about all the other positions that it does understand? Also, you seem to be putting Hiarcs in the "Knowledge based" program category and then saying that it can't be knowledge based because of the one position. Why did you pick Hiarcs to begin with. Some people may say that it is only one of the "Middle of the road" programs that is a mixture of knowledge and search speed. But what about a program that searches only 200 nps but plays 2100 level chess? Is this probably a knowledge based engine? What if it still can't understand the one position you mention? The speed of 200 nps would not qualify it as a "Fast searcher". What if you take this same program and increase it's speed to get 6000nps and now it's playing 2600 chess? What will make it a "Knowledge based" program? Suppose it still cannot solve your specific position then what? Jim Walker
