I want to create a complete repertoire for White and Black based on the French Defense. So I have two questions:
1) Which do you think is more similar, especially in pawn structure, to the French: the QGD (perhaps particularly the Ragozin var.), the Tarrasch, the Semi-Slav, the Dutch (i.e., Stonewall), or something else?
and 2) What is most similar with White? I'm thinking of 1 d4 with 2 c4, for similarities of pawn chain and their pawn-thrusts of c4 and c5 respectively, but what else should I consider?
I appreciate your input.
None of the ones you list!
The French is best known for its blocked center and play on the wings. Pawn chains, and attacking in the direction in which the pawns point are key to the French Defense, hence White's Kingside attack and Black's Queenside play with no real central counterplay.
The solution is to go with the d4-opening that also leads to the blocked center, the King's Indian Defense!
The King's Indian plays the same way as the French. The center is blocked, and the play is on the wings. Each side attacks the side to which their pawns point, and so White will go for a Queenside attack and Black a Kingside attack in the Mar Del Plata.
There are also many former GMs that played both defenses. Top of the list would be Wolfgang Uhlmann. Another big name would be Igor Glek.
As far as playing White, I would suggest sticking with 1.e4. There are lots of lines similar in nature, maintaining a fairly closed position. These include:
Advance vs Caro-Kann
Whatever line you understand most against the French
Closed Sicilian
Slow Italian
3.f3 against the Pirc, leading to a Saemisch King's Indian
3.c4 against the Modern
