R \| \| x . . \| uppercase: ours \| . x . \| \| . x . \| \| . x . \| \| . x . \| \| . x B \| +-------+ +-------+ +-------+ +-------+ +-------+ no no yes no yes The value of our top pawn depends on our ability to advance our bottom pawn, levering their blocker. Previously, this pawn configuration was always scored as passer (although a blocked one). Add requirements for the square s above our (possibly) sacrificed pawn: - s must not be occupied by them (1). - If they attack s (2), we must attack s (3). - If they attack s with a minor (4), we must attack s with a minor (5). The attack from their blocker is ignored because it is inherent in the structure; we are ok with sacrificing our bottom pawn.
