Winning plan for black in this line of French Defense: Advance Variation Main Line I play the French Defense as both white and black. I often play this line with black suggested by Korchnoi if I am not wrong. I have found a way to prevent the sudden b4, via Bd7 (if 8.Rb1 Bd7 9.b4 cxb3 10.Nxb3, I can answer with 10...Ba4, pinning the queen and winning material).

The problem is, although I feel comfortable with the limitations white has in development, I do not often find a winning plan as black and I end up finishing by playing for a draw.

What are your thoughts as to what I could do here?
Once stuff has settled down on the queenside, you may eventually castle there and create play on the other sector, with moves such as ...f6 or ...f5 Take a look at a few illustrative games that may help you understand how to put this into practice
