Smothered mates: common questions

What is a smothered mate in chess?

A smothered mate is a checkmate given by a knight to a king that is surrounded by its own pieces. The king has no square to move to, and a knight check cannot be blocked.

Why is a smothered mate always given by a knight?

The king is walled in by its own pieces, so no rook, bishop or queen has a line to it. Only a knight can jump over the wall.

What is Philidor's legacy?

The best known way to force a smothered mate. A double check from the knight and the queen drives the king into the corner, the queen is given up beside the king so that a rook has to take her, and the knight mates.

How do I spot a smothered mate?

Look for a king in the corner with its own pieces around it and one of your knights close by. If one square beside the king is still free, look for a sacrifice that makes an enemy piece fill it.
