I think Bookup does what it says but sometimes these results can be surprising.
I wouldn't trust the evaulations without looking at the lines which follow. As
far how a position should be valued, I think this is in large part a matter of
taste, personally, I don't see much difference between "unclear" and "equal". It
depends on who's doing the classifying.
