I hear so many amazing opinions about knowledge inside chess programs. Yes diep is dead slow, but that's because it scans a lot. However when you talk about patterns then you can see all the knowledge in Theta(log2 n). So 100000 patterns, just take the 2 log out. that's 16 times slower than a normal evaluation (with the same datastructure that is). Best regards, Vincent
