This is a fool's mate. It includes 2 moves. You need to be black for this. The following moves are made on the fool's mate: f4 e6 g4 Qh4# But try not to apply this tactic if your opponent is strong. The weakness of the f-pawn opens a diagonal, but the g-pawn can block it. When the g-pawn moves forward, there is nothing to block the queen on that diagonal and the king cannot go anywhere. The result will be checkmate.
