Bishop's opening - avoiding positional lines as Black after 2...Nf6 3. d3 I'm currently experimenting 1...e5 against 1.e4 aiming at the Petrov but I sometimes encounter Bishop's opening 2. Fc4 to which I reply 2...Nf6.

If White play 3. Nc3, I have some ideas, but if they play 3.d3, it's another story since after 3...Nc6, White can play 4.Nf3 that leads to a positional Two Knight's. 
And playing 3...Bc5 leads to a Guoco Pianissimo which I want to avoid at all cost. 

Are there some interesting lines here for Black considering the above ? Even if it's slighty inferior. Thanks

3...c6 is in my opinion by far the best move here. Usually white would continue with something like 4.Nf3 Be7 5.O-O (5.Nxe5 Qa5+) d6. 5...d6 is a more solid choice but 5...d5 is another option if you want to blast open the center quicker. For a nice game with 5...d6 played, take a careful look through Gelfand - Yusupov, Munich 1994.
