Chess Puzzle of the Day

Best move: Qxh7+

1.Qxh7+! Nxh7 2.Rf3-h3 and Rh8#

Philidor's Legacy is the 'smothered mate' pattern: the queen is sacrificed to lure a defending piece into smothering the king's escape. After 1.Qxh7+! Nxh7, the knight blocks h7 and then Rh3-Rh8# is a back-rank mate. This beautiful pattern has appeared countless times in top-level games.
