French Defense, Tarrasch Variation

The Tarrasch begins with 1.e4 e6 2.d4 d5 3.Nd2. In algebraic notation, Nd2 means that the knight from b1 moves to d2. From there it protects e4. Because the knight does not go to c3, Black does not obtain the characteristic Winawer position with 3.Nc3 Bb4. Black can still play ...Bb4 in some lines, but White usually answers c3 and the structure is different.

The move also leaves the c2-pawn free to advance to c3 and reinforce d4. The cost is that the d2-knight temporarily blocks the c1-bishop and occupies a less active square than c3. White normally solves this by developing the g1-knight to f3 or e2 and relocating the d2-knight later, once the center becomes clearer.

Black has two main replies. With 3...Nf6, Black attacks e4 and often reaches a closed center after e5. With 3...c5, Black challenges d4 immediately and may produce more open positions after exchanges on d5. In both cases, Black seeks active pressure against White's center within the French Defense.

3.Nd2 chooses the Tarrasch: it defends e4 and avoids placing a knight on c3 in front of ...Bb4.

The knight's route defines the family

White can protect e4 in several ways, but each one gives Black different options.

1. 3.Nd2 chooses the Tarrasch: it defends e4 and avoids placing a knight on c3 in front of ...Bb4.
2. 3.Nc3 allows the Winawer with ...Bb4 or the Classical Variation with ...Nf6.
3. 3.e5 closes the center immediately and leads to the Advance Variation.

The Winawer Variation requires 3.Nc3 Bb4. By choosing 3.Nd2, White avoids that structure but accepts that the pieces on the queen’s side may take slightly longer to leave their starting squares.
