Every page is also served as markdown at its URL plus .md. Fool's mate is the quickest checkmate possible. The pawns on f2 and g2 are the guards of White's king diagonal at the start. Fool's mate is the quickest checkmate possible: Black mates on the second move with Qh4 after White has pushed the f and g pawns, which leaves the king's diagonal wide open. The pawns on f2 and g2 are the guards of White's king [diagonal](https://georgelichess.com/glossary/diagonal.md) at the start. Move both, and the diagonal from e1 to h4 is open to a black queen. After 1.f3 e5 2.g4, the queen swings from d8 to h4 and the game is over. Why can't White defend? The queen's check comes along the diagonal, and the only [squares](https://georgelichess.com/glossary/square.md) on which White could block it, f2 and g3, cannot be reached by any white piece. Nothing can [capture](https://georgelichess.com/glossary/capture.md) the queen either, and the king has no square because its own pieces sit around it. So two moves each are really all it takes. This mate is more of a lesson than a threat. Informed opponents will not walk into it, and nobody plays f3 and g4 on purpose. What it teaches is that the pawns in front of your king and the diagonals leading to it deserve respect, even in the [opening](https://georgelichess.com/glossary/opening.md). Every move that loosens the king's cover should have a reason. To avoid it, develop with central pawn moves like e4 or d4, bring out your pieces, and think twice before touching the f-pawn and g-pawn together. In the diagram, after 1.f3 e5 2.g4, Black plays Qh4#. The queen travels from d8 to h4 and checks the king on e1 along the open diagonal. Also called: two-move checkmate. ## Example position Black to move plays Qh4#. The queen goes from d8 to h4 and checks the king on e1 along the diagonal that f3 and g4 left open, and White has no way to block or capture. Position (FEN): `rnbqkbnr/pppp1ppp/8/4p3/6P1/5P2/PPPPP2P/RNBQKBNR b KQkq - 0 2` It sits close to [Epaulette mate](https://georgelichess.com/glossary/epaulette-mate.md). An epaulette mate is a checkmate in which a queen checks a king whose two side squares are occupied by its own pieces, usually rooks, so it cannot step sideways. It sits close to [Scholar's mate](https://georgelichess.com/glossary/scholars-mate.md). Scholar's mate is a four-move checkmate on f7: White's queen and bishop both aim at that square, where only the king defends, and Qxf7 ends the game when Black overlooks it. Compare it with [Legal's mate](https://georgelichess.com/glossary/legals-mate.md). Legal's mate is an opening trap in which White lets Black capture the queen and then checkmates with a bishop and two knights, punishing a Black player who takes the offered piece.
