The wK moves to self-unpin the wS. The position taken by wK specifies which of the two bS moves at B2, to open a bQ line and self-block. The bQ would in fact have two ways to reach the square e2 at B4 but must be able to move at B3 without giving check. Reciprocal dual avoidance also at the moves W2 of wS, which must not interfere the bQ at W3, so as not to prevent bQ to self-block at B4. Model mates (author)

Black sacrifice at B2 with square clearance to play W2, self-block at B3. Dual avoidances, model mates.
If black sacrificed the bSd7 at B2, the only move left to self-block at B3 would avoid the mate for black line opening. The tries fail because the bSd7, which must self-block, is captured. Cyclical exchange of functions (wSa5 / wRe1(wBe1) / wSb8) - capture and guard / passive guard / mate (author)

The twinning mechanism allows black to guard in turn one of the mating squares, thus specifying the play. The wR unpins a bP and becomes once the front piece and once the rear of indirect white batteries, firing to the same square (b3). The two wS guard the flight (c3) where the bK must move. To allow this, the unpinned bP captures a wS, in turn, at B2 and the other wS abandons the guard by moving at W2. Exchange of functions (wSb5/wSd5, Captured / Interfering + Line opening). Exchange of functions : wQg8/wRc7, Rear piece of a battery / Mate (author)
After a white line opening at W1, one of two black pieces moves twice; first to unpin a white unit, then to self-block on the same square. Dual avoidance at W2 for mutual wR/wB interference at W3: the unpinned piece moves along the opened line, but doing so it cannot stop one square earlier, because it would interfere the other white piece at W3 (author)
