Philidor's mate
Philidor's mate, also known as Philidor's legacy, is a checkmating pattern that ends in smothered mate. This method involves checking with the knight forcing the king out of the corner of the board, moving the knight away to deliver a double check from the queen and knight, sacrificing the queen to force the rook next to the king, and mating with the knight.
The technique is named after François-André Danican Philidor; this is something of a misnomer, however, as it is earlier described in Luis Ramirez Lucena's 1497 text on chess, Repetición de Amores e Arte de Axedrez, which predates Philidor by several hundred years.An example is to be found in the game Jan Timman–Nigel Short at the 1990 Tilburg tournament. From the diagrammed position, play continued 27. Nf7+ Kg8 28. Nh6+ Kh8 29. Qg8+ Rxg8 30. Nf7#. (Note that White would force mate even if his rook, and pawn on e7, were removed from the board, and Black had a knight on f6. In that case, 27.Nf7+ Kg8 28.Nh6+ Kh8 [28...Kf8 29.Qf7#] 29.Qg8+ Nxg8 [or 29...Rxg8] 30.Nf7 still mates.)Opening traps
Occasionally, a smothered mate may be possible in the opening of a game. One of the most famous, and most frequently occurring, is in the Budapest Gambit. It arises after 1. d4 Nf6 2. c4 e5 3. dxe5 Ng4 4. Bf4 Nc6 5. Nf3 Bb4+ 6. Nbd2 Qe7 7. a3 Ngxe5 8. axb4?? Nd3# (see diagram). Note that the knight cannot be taken because the pawn on e2 is pinned to the white king by the black queen on e7.
