C03 French Defense: Tarrasch Variation

C03 holds six named lines, all under the name French Defense. It leaves C00 (French Defense) with 3.Nd2. Lines of seven other codes continue from its position, the third-widest spread of the 19 French Defense codes. That final move, by the knight, opens a line for the rook on a1 and guards the pawn on e4.
