nice puzzle, it is called smoothered checkmate.

There are hundreds of puzzles on here with that pattern.

This particular form of smothered mate even has a name, Philidor's Mate.

Philidor's Mate rarely shows up in games against two masters because anybody that skilled knows to recognize it and protect against it.

It shows up occasionally in games for lower ranked players, but only if the players can see how to bring it about.

I actually got to use Philidor's Mate once in game here on gameknot. ( gameknot.com )
