Gioachino Greco - Game #12

 
Why is 11.Bxe4 bad and what is White's best move?


Thought process:
        Checks - Mate Threats - Captures - Threats

The attack is simple. The defense requires more thought, but if you examine checks first, the solution pops right out at you.

11.Bxe4?? Bh4+ 12.Bf2 Qxf2#

11.Qh5+! g6 12.Bxe4 Qxh1+ (...Bh4+ loses) 13.Bxh1 gxh5.
