Sorry about the double post. I feel that endgames (even puzzles of endgames) are better appriciated here for reasons I rather not get into...

Anyway, here you go.

Qxh6, gxh6 (otherwise Nf6+, gxf6, Qh7#), Nf6+, Kh8, Rh7#.

EDIT: That's not the right solution, after Ra6.

Start with Qxp . . .

Nf6 leads to mate in all variations.

Wow, I never saw 1.Qxh6. Like Goldendog posted, I found 1.Nf6 which is more forcing since every move is check. 

I didn't see that either.

The puzzle is nice, but the title is even nicer. Can opener. Very descriptive. Imagine how you make Black displace his g7 pawn.

The first thing I saw was Qxh6
