Nice rule but it seems that this rule does not work when the pawns are at d5 and
a6.

The black king can stay at d6 and the bishop at g1-a7 when the pawn at a6 helps
black to prevent Ka6.

I thought that with 3 pawns the king can go from f5 but it seems that this is
also impossible.

Going with the king to f6 without sacrificing a pawn is impossible because of
Bd4 and after sacrificing a pawn white needs a better square.

It is possible that I miss something but together with Yace I could see nothing.
