Only the BB vs NN should show a big advantage, and it is going to take
*many* plies before it happens. Hence the discussion about this type of
ending in the ICCA Journal article.  I've modified 15.20 so that in the
last position, it now says about -.6 if you just set the position and
type "score"...  the others are about -.2 when black has a bishop and
white doesn't.
