Gioachino Greco - Game #4

 
White to move and win.

Thought process:
        Checks - Mate Threats - Captures - Threats

We can rule out Bxf7+, Nxg4, Qxf3 and quick checkmates.

The obvious tactical themes are defending the rook on h1 and trapping the enemy queen. 11.Nf2! does both in one fell swoop.
