Not so difficult: Qe6+ Qxe6 Nd7 Qxd7 Rb8+ Kxb8 cxd7 followed by d8=Q#
Well does that make me better than the professionals?

the key move is Qe6+! if black plays Kd8, then Rb8#.
If black plays Qxe6, then white plays Nd7! white is threatening Rb8 mate, and so black is forced to capture the knight with Qxd7.
Now here's the kicker: white sacrifices his rook too (!!) with Rb8+! Kxb8 is forced, and now white plays cxd7, with a checkmate on the next move.

after Nd7 black does not have to play Qxd7 it can just move Qh3 and then Qg2
something like this: Qe6+ Qxe6 Nd7 Qh3 Nxf8 Qg2#
The above post should answer your question.

No. The puzzle is set up so white has to win. It's easy for black to win, but we can't figure out how white sacrifices the queen to end up at checkmate without allowing the black queen to mate the king with the f1 knight and f3 pawn. It's easy to see black winning, but the puzzle says white has to win.

Quit the false modesty crap, Gowda (that was pretty damn difficult).
Some tactics which others find it easy, I find it hard. But this din take me even a min to solve it.
Because he had already given a clue of Queen sac, I searched for Q sacs: Qg4+ and Qe6+. Qg4+ is wortthless after hxg4 followed by Qh2#.
And Qxe6 was forced for black as otherwise black queen is lost.
With the two remaining pieces, only way mate could be setup was Nd7 and Rb8. so placed Nd7, but after Qxd7, it took me a few seconds to figure out that Rb8 would come first, then cxd7.
But overall, was it so hard?

Yes, it was very difficult (although of course the hint was a biggie).
You must be having a "Bad tactic day" today! Otherwise it would have taken you few milliseconds to solve it.
In a real game, there's no surety of there being a solution. When the post specifies a queen sac, it does make it much easier. (Though of course I first looked at Rb8+ followed by a queen sac, which got nowhere, and still didn't see Nd7 after trying Qe6+, but I'm no good at this game. 
)
I found the key and discounted it, had to look again.
In a real game -- depends on if it's 3 days or OTB. OTB, not very likely -- I'd just take the knight.

Ahem, solution? How does white win by sacrificing his queen?
This is a little known actual position from one of Anderssen's game (before we were born, of course), where white (Anderssen) sacrifices all his pieces to win.
And hsbgowd solution is the correct one.
I could do it because I saw it in a very old (my dad's) puzzle book - an all-time classic.

Agree.
In case none of you noticed, it's a PUZZLE. Black will always make the best possible move. White has to win. If you could cut your hypothetical chatter for one post, you could help me solve this puzzle so I can get on with my life.
Look at the diagram. Solve for white to sacrifice the queen and win.

Mottsauce GAVE you the solution in post 4, with a diagram, and with alternate lines which show why black with best play still loses. Any moves other than his "main line" lose even more quickly.
My chess club recently came upon a puzzle none of us could solve, not even our professional! If you can, please find the solution. It's a queen sacrifice mate, with white to move.
