As you leave the local North Pole pub, stepping into the starry night, a curious sight in the village square catches your eye. A group of reindeer are gathered around a giant chessboard.
One of the reindeer, Blitzen, glances up as you approach. "Ah, you're just in time," he says. "We've been trying to unlock this," he points his nose towards a door cleverly integrated into the f6 square of the chessboard. "But it requires a very specific chess move. We need to checkmate with the king on the f6 square on the 5th move."
Starting from the initial position, construct a game where Black checkmates on the 5th move by playing 5... Kf6#. You only have to provide one solution, even though there could be several. Give the whole series of moves.
