Compass theme

The black king and two black pieces alternatively occupy two squares X and Y in a 4-solution helpmate in two. The distribution of the occupation of the two squares X and Y may take several possible cardinal directions and it is helpful to use a compass to identify in which geographic zone the occupations are made by the black King and the black pieces.
