I'm not sure that is totally reasonable. Why? because if your bishop protects
the queening square and my bishop doesn't, you will _never_ get the pawn to the
queening square. Ditto for if my bishop defends the queening square. It is
just as good if it doesn't as blockades can happen anywhere along the file.
I think it more important to recognize that a pawn is blockaded and take steps
to break it, rather than just being happy about having a bishop that attacks the
ultimate promotion square.
