What a game!  The French Winawer is a dynamic opening, dangerous for both sides.  White overreached, and made some bad choices.  I pursued a simple plan that resulted in two black queens side by side in the corner of the board.  The analysis is my own and not a computer's.  Enjoy.

Nice. I liked how you sac'ed your advantage in material (a whole rook! not to mention nearly all your pawns) just to make way for the killer a-pawn. Bold stuff.

white needed to play a3 like on move 5

or dxc5 on move 6

You may be right eaglex.  If white doesn't know the theory of the Winawer very well, 5 Qg4 may be too risky.  The mainline is 5 a3 Bxc3 6 Qg4.
