Opening Repertoire Help

Hi community,

I need your help:

I'm going to go to a tournament next friday(Friday 22 july, 2011) (my opponents will be as good as I am ( ~my age)),

and I thought about the Ponziani as my main opening ('cause most of my opponents won't know how to play it right), so I need theory behind it.

I also need a short repertoire for black which should be easy to learn because I don't have that much time.

I would be very happy if you could help me

Yours, fegchess1
