Pin mates. The same specific fairy condition nullifies the checks to wK by bQ and effects the mates to bK by wS in both the phases. Orthogonal-diagonal roles played by all pieces (bK moves, wR/wB moves, checking lines by bQ, mating lines by wS). (Authors)
Face to Face: When a white piece is just one rank below a black piece on the same file, they exchange their walk.
