Puzzle - Mate in 5 - #001

Question

I've been writing some chess puzzles lately and I thought I would post some of them up here. I'm quite fond of this one so I thought I would share. I traditionally am not a fan of problems that are a "Mate in X," especially when it's in five, but the position, I think, is aesthetically pleasing. The real problem isn't the mate, in my opinion, it's setting it up.

1... Bc6 

White to move and force mate in 5 moves.

I'm inspired by a number of games, but primarily Alekhine vs Janoski, 1924 New York.

Note: Only recently have I learned that problems and puzzles are accepted here and I believe it to be a better community for them.

Answer 1

Nice mate!

1... Bc6 2. Bg5+ hxg5 3. Qxg5+ Kf7 4. Nd8+! Qxd8 5. Qg6+ Ke7 6. Qe6#

The mate is identical if 4... Rxd8 is played instead. The key idea is to force a piece onto the d8 square in order to cover the two squares the queen on e6 cannot cover - f8 and d8.
