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)

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)
