1st rank is cleared to allow mating by boh castlings. Black pawn promotes to the same type of piece as is captured, remaining white S or B pins itself on e-file and isn't used in mates. However the whole concept seems to be very original.

Direct royal battery is constructed and subsequently fired, on the way some white pieces are eaten by bK. Thematical twinning gives the paradox - to mate Black, White has to rush with his king to the square occupied by wK in the initial position of the other phase.

Cycle of white moves with tempo motivation: Black needs 2 moves to allow any of three prospective mates, but White lacks tempo moves. So White must check so that Black can parry the check immediately.

Black Se5 is pinned in two different directions, but the point seems to be in the required jump of Sd4 - he must move away to get guard of b6 by wB.

The order of black moves is determined by required anticritical character of first moves - White simply has to move along the battery line to avoing its guard after firing the battery.

In the initial position bQ is pinned on the long diagonal by wB. In the mates, however, the same bQ is pinned by wQ on the orthogonal lines, while wB pins bR in the a) position and … sleeps in b) position. Double pin mates are OK.
