It was interesting to me that, not only did they not believe in manual eval tuning, they also didn't believe in manually constructed opening books. All the opening stuff was learned, too. It's an interesting approach. It's probably better than having an amateur like me tweak things by hand, using a little bit of chess knowledge and intuition. But if you have a GM to help you out (as Roman and others have done for Bob), then I think you can make quite a bit of progress - these people have their own finely tuned eval function that has terms you might not even think to include (and if it's not included, its proper value cannot be learned). Next best thing to actually having GM advice is at least to have strong players match your program and demonstrate where it is weak - which is quite possible on ICC. I also think opening experts can add value, in a similar way. --Jon
