Fool's Mate is the shortest possible checkmate in chess. Black delivers it after only two moves by each side.

The game runs 1.f3 e5 2.g4 Qh4#. White’s king is mated because the f- and g-pawns have left the e1–h4 diagonal completely undefended.

Black's queen on h4 delivers mate along the open diagonal; white's f- and g-pawns have left the king without defenders."}

The mate succeeds only because White voluntarily opens the most dangerous line to the king. In any normal game the f-pawn stays on f2 and the g-pawn on g2, so the queen cannot reach h4 in two moves.

Club players occasionally see this pattern when an opponent tries an eccentric first move such as 1.f3 or 1.g4 and then compounds the error. The same idea can appear later in the opening if White creates similar weaknesses on the kingside, but the two-move version remains unique to this exact sequence.
