One way for White to proceed here is 1 Rxf6 hg 2 Rxd6, and even after 2... Nd6 he will still end up with a material advantage. But there is something more incisive (as they say):

you should have made it a puzzle

I tried (don't seem to be able to figure out how to hide the moves though). :(

You have been here for nearly two years and you haven't work it out yet ?! 

OK, Mr Weisenheimer, tell me how it's done.

hey ! btw who is Mr Weisenheimer ? and I am no expert installing puzzle either let alone I am having a hard time to insert a game/puzzle with diagram (I know how to do it) but by the time I put all the variations and comments I can't even 'insert' the bloody thing when I was done ! lol

Now to do the puzzle

 step 1. click on 'puzzle,problem or challenge to be solved'
 step 2.  you can set it up from a blank board or the full set up, or use the              fen/pgn
step 3. after you made the choice, say you are using 'blank board' you can re arrange the pieces then when you are happy with starting position click 'enter moves' 
  step 4. then you can make your moves the way you want the peoples to solved the puzzle when that done click 'continue'
 step 5. you can put some info in it and next stage size/colour when you are finish and preview it you can click on 'insert'

tip; you can practice this by sending a message to yourself to see if it work by using the 'message'.

  Hope that help, good luck.

Thanks!  The emendation has been made.

Rxf6 Kg8! losing, but surviving =D

Also, its a mate in 5 from gxf6.
1.Qh7+ Ke6 2.d5+! cxd5 3.Bh3+ f5 4.Qxf5+ Ke7 5.Qf6#

also I see after Rxf6+ Qxf6 surviving for black but still not good though

Kg8 isn't surviving for long...but nice find on the mate in 5!
