This is a special kind of bad bishop, the bishop is permanently dead.  It would
be easy to write something that could understand that the bishop is dead, but it
would be hard to execute the code hundreds of thousands of times per second.

Put black's f7 pawn on g7 and black is suddenly doing lots better.
