1.Bxh6 f6
  My first reaction to this move is, it is a pretty "underwhelming"
  response after your opponent has just clipped you for a pawn. How
  can this be right? A pawn AND you let me keep the 2 Bs?
2.Rxf6
  This is a perfectly natural response.  It often the case that with
  a pair of  rooks or knights, there is a certain "redundancy of
  activity", so sacing one is often quite effective. The 2 Bs are a
  different story altogether. Plus the black rook on a8 is key to
  motivating everything.
2...gxf6
  2...gxh6 3.Qxh6 wins easily as does 2...Qh5 3.Bxg7 Kxg7 4.Rg6+
3.Rxf6 Qh5
  Nothing comes close to working now: 3...Rd8 4.Qg5+ Kh8 5.Rxe6
  and 3...Bd7 4.Qg5+ Kh8 5.Qh4 threatening 6.Bg7+ are easy, while
  3...Rf7 4.Rg6+ will quickly mate.
4.Rg6+ Kf7
  On 4...Kh8 5.Bg5 is simple.
5.Rg7+ Kf6 6.Qf4+ Bf5 7.g4 is pretty gruesome.
