Fool's mate: the fastest mate in chess

Two moves by White, two by Black, and the game is over. The fool's mate is the fastest mate there is. It needs White's help, and that is exactly why it is worth knowing.

The moves

White moves the f-pawn and the g-pawn, the two pawns closest to the diagonal between h4 and e1. Black opens the way for the queen, and on the second move Black mates on h4.

Fool's mate: the queen on h4 gives check along the diagonal towards e1. The two pawns that should have protected the king have moved.

The king on e1 is surrounded by its own pieces. No white piece can block on g3 or f2, and nothing can take the queen.

Black to move and mate in one.

Eight roads to the same mate

There are exactly eight ways to give mate after two moves each, and all of them are the fool's mate. White can move the f-pawn one or two squares, and the g-pawn two squares, in either order. Black can open the way for the queen with e5 or e6.

  • 1. f3 e5 2. g4 Qh4#, and the same with 1… e6
  • 1. f4 e5 2. g4 Qh4#, and the same with 1… e6
  • 1. g4 e5 2. f3 Qh4#, and the same with 1… e6
  • 1. g4 e5 2. f4 Qh4#, and the same with 1… e6

Why it doesn't work

The fool's mate isn't really a trap, because Black can't do anything to lure it out. It is White who makes two bad moves. Anyone who knows that the f-pawn and the g-pawn shelter the king, and doesn't move both of them at the start of the game, will never run into it.

The lesson still matters. The pawns in front of the king are its shelter. Move them with care, especially the f-pawn, and look at which diagonals open up.

With the colors reversed

White can give the same mate, but it takes one move longer, because White moves first. When Black has made the two bad pawn moves, it is White's third move that mates.

With the colors reversed: Black has made the same two moves. White to move and mate in one.

Why is it called the fool's mate?

The English chess book of 1618, where the scholar's mate also has a chapter of its own, describes the mate in two moves. If the scholar's mate is a mate for peasants who can't play, the author writes, then this one is a mate for fools: the fools mate. It has been called that in English ever since. In the book Black's king's pawn moves only one square:

Frequently asked questions

What is the fool's mate?

The fastest mate in chess: White moves the f-pawn and the g-pawn, and Black mates with the queen on h4 on the second move, for example 1. f3 e5 2. g4 Qh4#.

How do you avoid the fool's mate?

By not moving both the f-pawn and the g-pawn at the start of the game. They guard the diagonal between h4 and e1.

What is the difference between the fool's mate and the scholar's mate?

The fool's mate comes after two moves and needs White to make two bad moves. The scholar's mate comes on the fourth move, and there it is enough for Black to miss a threat against f7.
