Nope, cuz of 3…NxQ! D’oh!
However, White has perpetual checks with 3 RxN+ in your line.
White can also try 3 Qh6+ in your line and if black plays 3…Rg7, then 4 Qf6+ with perpetual checks, but then black could try
3 (Rh8+) Ke8?!
4 RxN+ Kd7
5 Qe6+ Kc7
6 RxN+ RxR
7 QxRf7+ Kb6
8 Qa7+ Kb5
9 Nd4+ with a royal fork, so black is better off with 3…Rg7 forcing the draw; and white is better off with 3 RxN+ forcing the draw, to not give black chances in case 3 Qh6+ Ke8 gives black some trick to escape that I missed.
Btw, black can also play:
1 (Rh8+) Ng8
2 RxN+ KxR
3 Qe8+ Bf8 (…Rf8 Qe6+ Rf7 Qe8+ etc)
4 Rg1+ Rg7 (…Kh8 Rh1+ etc)
5 Qe6+ Kh8
6 Qh6+ or Rh1+ with perpetual checks.
Don’t see a win for white anywhere; white better just take the draw.

3…NxQ is illegal: the knight is pinned.
1. Rh8+ Bxh8
2. Rxh8+ Ng8
3. Qh6+ K e8
4. Rxg8+ Kd7
5. Qe6+ Kc7
6. Qxf7+ Kb6
7. Rxb8+ Nxb8
8. Qa7+ Kb5
9. Nd4+ Kc4
10.Nxb3 axb3
11.bxc3 Kd3
12.Qxb8 and white has an easy win.
Robert has a nice solution, but a slight change in move order is more forceful:
1. Rh8+ Bxh8
2. Rxh8+ Ng8
3. Qh6+ Ke8 (The discussion around 3. Qxd6 Nxd6 and “do’h” and the knight being pinned and all seems to be the result of an hallucination. 3. Qxd6 is bad because of 3. … Kg7. There’s no Black knight available for “3. … NxQ.”)
4. Rxg8+ Kd7
5. Qe6+ Kc7
6. Qxf7+ Kb6
And now:
7. Qa7+ Kb5
8. Rxb8+ Nxb8 (8. … Kc4 9. Qd4#)
9. Nd4+
… winning the queen and leading to an exchange of knights with White’s queen free to clean up the pawns.

Oops! I must have been half-asleep again — I set up my board wrongly for that one.
Looks to me like jcheyne has it right: the analysis looks flawless to me.
Just to let you know that I’m not insane — I placed a black knight on c8 instead of a6. Were there a knight on c8, then Rh8 would be the saving drawing move, as I babbled above. With the knight on a6, white wins with the same move.
Its all about boring tactics. Chess isnt only tactics you know. Very boring to put the pieces all the time. Please give some mate in 1 move.
1)NxR
QxN or NxN
2)RH8
BxR
3)RxB check
Tvtom…there is no perpetueal afetr 3…Rg7. White simply plays 4. Qxd6 and wins. The variation that robert pointed out is the correct (and forced) variation.

Yeah, I set the position up on my board and put one of black’s knights on c8 instead of a6 (reflected symmetrically across the long diagonal), and so my comments only apply to my mistaken set-up.
Chysslexia strikes again!
