HOTF through four twin positions, with white direct unpins in B1, diagonal-orthogonal echo, two pairs of reciprocal tries. In a) and b), each unpinned piece moves to open a gate and to take some flights. Both in a) and b), a try fails for anticipatory black interference, preventing the interfered piece to selfblock in B2. In c) and d), vice versa, the unpins are combined with black interference, to allow the unpinned piece mates (author)

The white clears a square at the first move so that the black can move and become checkmate.

Two pairs of solutions with reciprocal change of W1/W3 in each pair. In each pair, WQ change its functions, playing on the same square: W1 - sacrifice, W3 - mating move. Also, in a similar way, WB change its functions, playing on the same square: W1 - mating move, W3 - anticipatory supporting of mating unit (author).
Две пары решений. Чередование первых и третьих ходов белых в каждой паре. В каждой паре перемена функций в игре белого ферзя: W1 одного решения - жертва, W3 во втором решении - матующий ход, и все на одном поле. Также, аналогично, перемена функций в игре белого слона в каждой паре: W3 матующий ход в одном решении - и этот же ход - первый в другом решении, (упреждающая поддержка матующего ферзя), игра также на одном поле (автор)

1st sol: two-moves long escape of white bishop into hideaway without switchback and with pure motivation: no purpose other than line vacation or clearance twice (neither captures, nor shielding, nor tempos, etc.). B-B and W-W Bristol. Two self-blocks. Introductory move is wB-bR ambush. Thematic anti-ambush: obstructing wB is placed in front of wQ.
2nd sol: reciprocal ambush - assisting wB is placed behind wQ. B-B interference and B-B Umnov. Different mates on the same square by different wQ’s moves in both solutions (author)
