The white king can be put into smothered mate if black plays Nc2#

Smothered mate is a chess term used to describe a type of checkmate. It occurs when a king is surrounded by his own pieces and is put into check. Most commonly employed for this mate is the knight. In the following epitome, the knight cannot be captured, the king is put into checkmate as a result, as it has nowhere to move. The king doesn't necessarily need to be checked by a knight; any piece could work as well. The king's escape squares just need to either be blocked by his own pieces or controlled by the enemy. Such is the case with a back rank mate in the corner; the king's escape routes forward are all covered by pawns and the whole back rank is controlled by the rook.
