Fool's Mate: The Fastest Checkmate in Chess

Fool's mate is the shortest checkmate possible: Black mates on the second move. It needs White's help, two pawn moves that open the king to the queen, and that is exactly why it's worth knowing.

Step 1 of 5

  1. Two moves

    Watch: 1.f3 e5 2.g4 Qh4#. The f-pawn has left the diagonal from h4 to e1, and the g-pawn, which could have blocked on g3, has gone past it. The black queen checks along the diagonal. Nothing can block it, nothing can take the queen, and the king has nowhere to go: checkmate.

  2. What went wrong?

    Which of White's moves made this mate possible?

    Question
  3. Mate as Black

    You are Black, and the board has turned round to your side. White has played 1.f3 and 2.g4. Punish it.

    Your move

    Checkmate in one move.

  4. The same mate for White

    It works the other way round too. Black has played 1...f6 and 2...g5, opening the diagonal from h5 to the king on e8.

    Your move

    Checkmate in one move.

  5. Don't fall for it

    Back to White. You've played 1.f3, Black has answered 1...e5, and the queen on d8 now looks at h4. One more careless pawn move would lose on the spot.

    Your move

    Make a move that doesn't allow mate.

What you learned

  • Fool's mate: 1.f3 e5 2.g4 Qh4#, the fastest checkmate there is.
  • Moving the f- and g-pawns early opens the diagonal to your king.
  • If your opponent makes the same mistake, the queen mates from h4 or h5.
