Reykjavik Open 2013 Rd1-King's Gambit

'In this day and age with advanced computer generated opening preparation why would a GM candidate play against the Muzio in a tournament game???'-Hans Jung-Chesstalk

This got me curious to see what happened in the game(See Chessbase Analysis on CBase.com too)

I put Houdini3.0 to work and found an improvement for black on move 12.

Position 1

Black has taken the offered knight in a Muzio Gambit and in the game played 12...Bd6?? to lose by force. What would you recommend in hindsight?
