Pawn Center Easily worth the Exchange Sacrifice

In the following French Defense played at the internet chess club, Nooky from the United Kingdom is "up the exchange" handling the White pieces. However, with proper play Black should come out on top owing to his suffocating pawn center comprised of the e4, d4, and c5 pawns.

White just played b3 to protect his pawn from capture by the the Black Rook at b8. While this protects the pawn, it creates a weakness on the c3 square for occupation by, perhaps, Black's f6 Knight after it hops to d5.

Also, the h1-a8 diagonal will be terrorized by the light squared Black Bishop.  It is crucial to recognize that both of White's Rooks are impotent due to the lack of open files. Also the Black pawns are lusting to expand Aron Nimzovitch which will weaken squares for occupation by the Black forces.

Hopefully the reader will now be more convinced of the value of an advanced, difficult to dissolve pawn center as in this case it is worth more than being "down the exchange".
