Good attack or defense against ponziani opening.

Could you guys help me to find a good opening against the ponziani opening?

you'll find something in there 

I think d5 is the best continuation for black but don't take my word for it

The correct move after 3. c3  d5  is 4. Qa4

After 3. c3  d5  4. Qa4  f3  5. Bb5  Ne7  6. exd5  Qxd5 White should probably play 7. d4

instead of 3...d5 i prefer 3...f5, its sound according to my computer analysis and its very ambitious... the computer actually tends to get a better position with black when i match up the computers from my analysis. White has to react immediately, also the fact its less familiar opponents arent prepared, its what i play and i never had any major issues in the opening and when i do i just put it in the analysis, the reason i reccomend it is its fun to play also and leads to good attacking positions

I think Black is significantly worse in the 3...f5?! line after 4.exf5, what move do you suggest to equalize for Black there?

I am studying  the lines after 3. c3  f5 and hope to have a ton of analysis next time we get a vote chess game with this line.
