Hint
Hovedmotivet i denne oppgaven er Swallow's tail mate.
In swallow's tail mate, a queen checkmates the king. The queen is orthogonally adjacent to the king. The king is not on the edge of the board. The two escape squares not guarded by the queen are blocked by its own pieces. A swallow's tail mate is also possible with a rook, when other pieces guard the additional escape squares.
