Philidor's Mate

I watched this game online and decided to post it since it has a classic mate, named for the great French chess champion. I thought this might be of interest and even instruction  to beginning players.

 Yes, but I think this method of queen sac is called Philidor's mate.

There are many 'smother' mates. This particular mate is of historic interest because it's one of the first recorded and generally attributed to the player who called himself 'Philidor'. Saying the Philidor mate is a smother mate is like saying the Ruy Lopez should simply be called a king's pawn opening.

Thanks chawil, independently the name of the mate, the game is very instructive. In the Stonewall Dutch, when Black starts opening the center successfully is probable that White has not played well.

chawil: according to your thought this might be of interest and even instruction  to beginning players, I have added other comments to some moves:

9. f3?! The following game development illustrates that this move weakens the White king's position. 10. Bb2 dxc4 Starts opening the center. 16. Qd4?Allows the following improvement of black bishop's position and loosing time. 18. Ncxe4? Starting a wrong exchange loosing material and the game. 21. Rf4? The exchange of rooks weakens the f file and allows the following typical mate maneuver.
