I disagree. I do not think that a program with a lot of knowledge is going to perform poorly against Fritz. If knowledge can help kramnik to beat Fritz I see no reason to assume that it cannot help a chess program. The problem is simply that the programmers do not know how to teach programs the relevant knowledge. Uri
