Schematically matched solutions. In the first solution, the bishop participates actively in the self-blocks by moving to c6. In the second, the rook actively participates in the self-block by moving to d4. In each case, the queen moves to a different square (e5/e6), but the rook serves as a block to the queen's capture of the knight, the obvious mating piece in such a miniature. There is also correspondence between the kings' moves - d6/d8, and d5/d7. (Author)

Black critical moves, black selfpin, interferences, pin mates. To obtain the longest black moves and to avoid the use of stoppers on the diagonals, I feel it is necessary to capture the Te1 in one solution. The twin mechanism echoes the B1 moves. I found also a position 2.1.1.1 but with a single weak promotion to D, while I prefer to use the Th1 for mate. (Author)
