Djurasevic theme: in the trial, key A + threat B + 1st variant C + 2nd variant D.
In the real game, key C + threat D + 1st variant B + 2nd variant A.
So ABCD-CDBA.

5 - #3 strict Growing Men
Bissicks, P.2017
white Bf1 Ke2
black Rc7 Kg8
#3 strict Growing Men(2+2)
strict Growing Mena unit must play a move geometrically of strictly greater length than the move it played before
to the move it played before.
Thus, the black king is immobilized, its position necessarily being the result of a castling short.
On the other hand, the rook comes (at best for her) from a8 via a7 and must therefore play moves of length greater than 2

To capture, a unit virtually passes through its original square.
In the particular case of fairy pieces, the supposed original square is the promotion square of the column it is on
Knight that can make several successive jumps in the same direction
Zebra (leaper (2,3)) which, like the Nightrider, can make several successive leaps
