Hardest tactic ever. 1 move checkmate
Sort:
The obvious thing that jumps to mind is dxe6+, but then ...f6. So it’s either a helpmate puzzle or the creator missed something, since no other checks lead to mate.
Why is there no White rook on the seventh rank?
Or queen
If black moved his f pawn to f6 qxg6 is checkmate
But I can't find checkmate in 1 move
Yes
If pawn was on h6 nh5 is mate
h5+ 
h6
g5#
