Making the giuoco piano interesting as white Does anyone have advice to give against the giuoco piano ? I find this opening boring for white after 3... Bc5 and I'd like to find a way to keep playing the italian without risking to play a boring game. I know the Evan's gambit, but I'd rather develop a repertoire on openings I can comprehend instead of relying on preparation. 
I'm looking for sharper lines that don't require sacrifices a computer or theorician would consider unsound. Would you recommend, 4. O-O, d3, c3, Nc3, or do I have to avoid the italian game completely ? That would be a shame because I enjoy playing against all other replies.
What about slow plan (1.e4, Nf3, Bc4, d3, c3, 0-0, Nd2), then depending on what the opponent does, you can play d4 or move the knight on d2 -> f1 -> g3 (and potentially f5) and make something happen on the king side.
