Steve, I wouldagree with you that writing a good score estimator is extremely difficult, probably as difficult as writing a computer player.
However, your argument of equivalence (if that is how I understand it) does not follow. Just because you can score any position does not mean you can therefore play well. If you could score all Go positions on the board, you still couldn't enumerate them all, or follow all branches in the tree. Personally I'd also rather see score estimate abolished. The comments of people in games (normally below 2d or so) are atrocious.
