First we ask -- what if Black had moved 1. ... Kf8  -- 
UhOh,
1. ...  Kf8, 2. Qd6#

So...
After 2. Rxg71!  black has several options, but no good ones.

2. ... Kxg7, 3. Qh6+  Kh8, 4. Qxh7#
2. ... Nxf4, 3. Rxh7#
2. ... Nxg7, 3. Qh6  any move, 4. Qh7#
or, as in today's puzzle,
2. ... Ng5, 3. Qxg5  any move, 4. Rxh7#

EDIT:  As ndskyking pointed out, by the time I actually submitted this,I had already figured out what happened if 1. ... Kf8, so the note below should have been deleted.

Now I want to look at the lines that would follow had black moved 1. ... Kf8.

I don't think I'm reading the post correctly duff.  It says you want to see lines that follow had black moved 1...Kf8, but you already posted the answer to that, 2. Qd6#

I think you meant something else?

Too hasty - played Nh6 like some others. I expected the queen to play a larger part in this one but at least she doesn't get sacrificed-makes a change. Black deserves to be mated just for getting in that state !

Nice!

Interesting (and fun) puzzle. As usual, I enjoy the comments as much as the puzzle. So today I offer a question as well: How in the world did black get into such a terrible position? <smile>
