Yes, I agree, if you do not know Ponziani theory it can be a bad opening for you.
I have shared some of the theory it is just that I am able to share a whole lot more theory in the group Ponziani Power.
The main purpose of that group is to learn Ponziani theory. Or learn enough so one can play the Ponziani on a practical basis. You will find our members quite enthusiastic about the Ponziani Opening and there are reasons they are enthusiastic.
pfren, you know a whole lot about many openings including the Ponziani.
But am sure you considered I may know some things about certain lines in the Ponziani that you may not know?
By this I mean published refutations to the Ponziani.
You do play a line 3. c3 Nf6 4. d4 exd4 5. e5 Nd5 which is a good line to play against the Ponziani but you and I do not agree 100% if it equalizes easily or not. You have experienced players playing bad moves for the White side of that variation. [I think]
