When looking at the problem, one recognizes a "not quite healthy" fir-tree. However, if one deepens a little bit into the position, one recognizes after a while that the last black move must have been Kf4-e3. So if we look more accurate this position before the last move, which has been done by black, then one recognizes that there is a completely "healthy" and beautiful "grown" Christmas tree on the board (author)

(Sf3+?)} Bf1*e2 18.Kd5-c6 Be2-f3 # {MM}

White choice in the key and black choice in the 10th move. The sacrificial move of black Knight: 17.Sf3+? gxf3 18.Kc6 Lg2#?? fails because the white Pawn stands in the way of his Bishop. Instead, there is a mate in the reciprocal field cast in the required traits number, ie: 17.Sxe2+! Bxe2 18.Kc6 Bf3# (authors)

I think the try 17.Sf3+? is pointless since the mate Lg2#?? fails not because that wP stands on the way of wB (after gxf3) but because the square g2 is occupied by another wP. Compare to | сравните с: yacpdb/67878 (director)

At present, the 2+1 concept is coming into fashion: a pair of matched solutions plus a third one as an antithesis involving certain thematic aspects from the first two. For example in this problem the third solution is a natural extension of the content – in it, all actions are antipodal! Two solutions feature battery play, while in the third the battery is eliminated. Two solutions: Phoenix and Pronkin in the third, assistance to promotion on the right square. 2 non-model mates and a model one in the 3rd solution!
Common point: both black thematic pieces perform the blocking! And capture of a piece on W1 (author)

Третье решение, в котором все действия – антиподы! Два решения - игра батареи, в третьем – разрушение батареи. Два решения - Феникс и Пронкин, в третьем - помощь превращения на нужном поле. 2 неправильных мата, а в 3-ем - правильный! Общий момент: блокируют обе тематические фигуры чёрных f4 и g7!
