Positions with connected pawns are the most complex case, and the result depends on the and of the pawns and the colors and locations of the bishops. If one of the pawns is a (on the a- or h- file) the position is normally drawn. If the pawns are on the opposite color as the defender's bishop, the defender may be able to blockade the pawns and draw. If both pawns can safely reach the sixth rank, they win unless one is the wrong rook pawn, i.e. the rook pawn that promotes on the square of the same color as the defending bishop .
