Smothered mate: the knight against a king with no air

In a smothered mate the king is hemmed in by its own pieces, and a lone knight gives check. The knight jumps, so the check can't be blocked. It is one of the most beautiful mates in chess.

What it looks like

The smothered mate is the knight's very own mate. The king usually stands in the corner, surrounded by its own rook and its own pawns. The knight gives check, and because it jumps, nothing can be put in between. If nothing can take the knight, it is mate.

Smothered mate: the king on h8 is hemmed in by its own rook and its own pawns. The knight on f7 gives check, and a knight's check can't be blocked.

The name says exactly what happens: the king is smothered by its own pieces.

White to move and mate in one. The king has no air.

The queen sacrifice on g8

The most famous route to a smothered mate takes a few forcing moves. The queen checks, the knight checks and drives the king back and forth between g8 and h8, and finally the queen is sacrificed on g8. The rook has to take, and now the king has shut itself in. The knight mates. The sacrifice is a decoy: the rook is lured to the square where it is in the way.

The combination is called Philidor's legacy, after the eighteenth-century French master François-André Danican Philidor. But the name is younger than the combination. It is already in a Spanish book by Lucena from around 1497, and the Portuguese apothecary Pedro Damiano showed a smothered mate in his book of 1512. The phrase Philidor's legacy seems to have first appeared in print in 1804, in an English book. Why Philidor's name was attached to it, nobody knows for sure.

White to move and mate in two. The position is from Timman–Short, Tilburg 1990.

Timman–Short, Tilburg 1990

The smothered mate is rare in real games, but it happens. At the Tilburg tournament in 1990, Jan Timman played the queen sacrifice on g8 against Nigel Short, move for move as in the textbook. A year later, in the same town, Short got his revenge with a king walk that has become famous: the king march in Tilburg.

See it coming, and defend

  • A king in the corner with no air. If the king is on h8 with the rook on g8 and pawns on g7 and h7, it has no squares at all. A single knight check is enough.
  • The square f7, or f2. The knight usually mates from there. Keep an eye on which of your opponent's pieces can reach it.
  • The diagonal towards g8. The queen sacrifice needs the queen to give check on g8. Close the diagonal, or trade off the queen or the knight.
  • Give the king air. A pawn that has moved one square, or a square not taken by your own pieces, and the pattern no longer works.

Frequently asked questions

What is a smothered mate?

A checkmate where the king is completely hemmed in by its own pieces and a knight gives check. Because the knight jumps, the check can't be blocked.

What is Philidor's legacy?

The most famous route to a smothered mate: the knight gives check, the queen is sacrificed on the square next to the king, a rook has to take and shuts in its own king, and the knight mates. The combination is older than Philidor, whose name it carries.
