French Defense: Tarrasch Variation
Initial Moves: 1.e4 e6 2.d4 d5 3.Nd2
Strategic Summary & Main Idea
The Tarrasch Variation defends e4 with the knight on d2 instead of c3: 3.Nd2 avoids the Winawer pin and keeps the c-pawn free for c3, at the cost of shutting in the c1 bishop for a few moves. It is the most economical line against the French, and the measurement places it below the others: +0.19 after 3.Nd2, against +0.62 for the Winawer and the Classical. The entry's useful figure is the gap between Black's replies. 3...c5 measures +0.18 and matches the starting position; 3...Nf6 measures +0.59, and the Guimard, with 3...Nc6, +0.73 — both cost almost half a pawn more.
The pawn structure this opening produces
The Tarrasch leads to two very different structures, depending on whether Black answers ...c5 or ...Nf6. After 3...c5 4.exd5, Black chooses the recapture. With 4...exd5, Black gets an isolated pawn on d5 after the exchange on c5: the classical isolated-pawn structure, in which Black has active pieces and open c- and e-files, and White blockades d4 with a knight and plays against the pawn in the endgame. With 4...Qxd5, Black trades the isolated pawn for a queen exposed in the centre, and White gains time attacking it with Bc4 and Nb3. After 3...Nf6 4.e5 Nfd7, the structure becomes the Advance chain: White pawns on e5 and d4, Black pawns on e6 and d5, and Black attacks the base with ...c5 and the head with ...f6. The difference from the Advance is that White's d2 knight must go to f3 or b3 before the c1 bishop can develop, and that Black's d7 knight is far from f6. In every version, the knight on d2 is the price of the Tarrasch: it avoids the pin, but delays a piece.
Typical Plans for White
- Against 3...c5, take on d5 and play against the isolated pawn after 4...exd5
- Against 4...Qxd5, develop with tempo on the queen with Bc4 and Nb3
- Against 3...Nf6, push 4.e5 and build the chain with c3, Bd3 and Ne2
- Against 6...b6, hit g7 with 7.Qg4: the position rises to +0.69
- Castle before bringing the queen to e2 in the 4...Qxd5 line: 7.Qe2 measures −0.03
Typical Plans for Black
- Answer 3...c5, which measures +0.18 and is the cheapest reply
- In the d5 exchange, accept the isolated pawn with 4...exd5 for active pieces
- Against 4.e5, retreat the knight to d7 and hit the chain with ...c5 and ...Nc6
- Never centralise the knight on e4 against 4.e5: 4...Ne4 measures +1.07
- Do not play ...b6 with the d7 knight away from f6: 7.Qg4 hits an undefended g7

Frequently asked questions
Is the Tarrasch weaker than the Winawer against the French?
By the evaluation, yes: 3.Nd2 measures +0.19, and the Winawer and the Classical measure +0.62 in the French entry. What the Tarrasch buys is economy of theory — no pin on c3 and no Poisoned Pawn — and a predictable structure. It is the choice for players who prefer stable positions to half a pawn of evaluation.
What is Black's best answer to the Tarrasch?
By the measurement, 3...c5, which measures +0.18. Within it, 4...Qxd5 (+0.14) costs less than 4...exd5 (+0.32), because it avoids the isolated pawn. The replies with 3...Nf6 (+0.59) and 3...Nc6 (+0.73) cost almost half a pawn more.
Is the Tarrasch isolated pawn good or bad for Black?
It is a trade-off. After 4...exd5 and the exchange on c5, Black has a weak pawn on d5 but open files and active pieces, and the position measures +0.32 after 9...Bd6. White wants to trade pieces and reach the endgame; Black wants to keep pieces and attack before that happens.
Common Mistakes & Where Most Amateurs Go Wrong
- 01 Centralising the knight with 4...Ne4? against 3...Nf6 4.e5. The piece has no support: 5.Nxe4 dxe4 leaves Black with an advanced e4 pawn that White attacks with Bc4 and Ne2, and the position measures +1.07, against +0.59 before the move. The line:
1.e4 e6 2.d4 d5 3.Nd2 Nf6 4.e5 Ne4 5.Nxe4 dxe4+1.07 - 02 Playing 6...b6? in the Advance chain, preparing ...Ba6. With the d7 knight away from f6, 7.Qg4 hits g7 and Black has no comfortable defence: +0.69, against +0.29 for 6...Nc6. The line:
1.e4 e6 2.d4 d5 3.Nd2 Nf6 4.e5 Nfd7 5.Bd3 c5 6.c3 b6 7.Qg4+0.69 - 03 Bringing the queen to e2 with 7.Qe2? in the 4...Qxd5 5.Ngf3 cxd4 6.Bc4 Qd6 line. The queen blocks the f1 bishop and Black develops with ...Nf6 and ...Nc6 at leisure: −0.03, against +0.14 for castling. The line:
1.e4 e6 2.d4 d5 3.Nd2 c5 4.exd5 Qxd5 5.Ngf3 cxd4 6.Bc4 Qd6 7.Qe2−0.03
