You should consider giving a diagram. I help but only if I get the diagram. I don't want a headache.
Ponziani Opening Forced Exchange Questions

Here is the primary diagram. This is the basic ponziani setup. It is black's turn in the position shown.

That is the classical ponziani defense, prescribed by the developer of this opening. Black can counter white's kingside attacks after 4.exf5 or 4.Bb5 but I don't think of my rating (1250s blitz) would take the risk of such a daring defense.
I have a feeling that after 3...f5, black would try to castle queenside. I don't know the theory though. Just a thought.
In the ponziani opening (1.e4 e5 2.Nf3 Nc6 3.c3) is it possible for white to force bishop-for-knight (lose knight, capture bishop) exchanges on black? I am specifically interested in exchanging the queenside knight for black's light bishop, although that might be asking for too much.
Also, under ponziani, if both sides castle short side by move 9, which one of black's bishop is more defensively active?
