I got all but the last move right on intuition 
knowing it was a study I guessed study-like moves... so I guess that doesn't really count for much. I figured it would be Nf3+, but didn't see why Kg3 didn't work.

Interesting ideas, especially the way Black can outmaneuver White and mate after 2 Kh2? f1=N. Of course, in the main line, 2 Kh3 f1=N, 3 Nf3+! Nxf3 is stalemate.
