French Defence

Seizes central space and opens diagonals for the bishop and queen.
Lock the center with 3.e5, fortify d4 with c3 and Nf3, and defend with 10.Nc2.
Key strategic themes, pawn chains, and piece maneuvers in the French Defence
After 1.e4 e6 2.d4 d5 3.e5, a locked central pawn chain is established. White controls more space on the kingside, while Black focuses all attention on undermining White's d4 pawn base.
Black attacks d4 systematically: first with 3...c5, then 4...Nc6, followed by 5...Qb6, and finally routing a knight to f5. White must defend d4 with c3, Nf3, and Nc2.
Black's light-squared bishop on c8 is initially blocked behind the e6 pawn. Common strategic plans involve activating it via ...Bd7-...Be8-...Bg6 or trading it off with ...b6 and ...Ba6.
If White plays 3.Nc3 instead of 3.e5, Black pins the knight with 3...Bb4. This forces complex imbalances where White gets doubled c-pawns and attacking chances against Black's king.
White's 3.Nd2 avoids the Winawer pin while keeping the c-pawn free to support d4. Black typically responds with 3...c5, challenging White's center immediately.
Once White's d4 pawn is securely held, Black often plays the thematic ...f6 break to chip away at the tip of the pawn chain on e5, opening the f-file for rook pressure.

The French Defence is a solid, counterattacking opening starting with 1.e4 e6 2.d4 d5. Black temporarily concedes space to build a resilient central structure and mount counterattacks against White's center.
White pushes 3.e5 to gain space on the kingside, restrict Black's f6 square, and establish a firm central wedge. The trade-off is that White's d4 pawn becomes a permanent target for Black's pieces.
Because Black's first move 1...e6 locks the light-squared bishop behind its own pawn chain, making it difficult to develop actively. Finding an effective role for this bishop is one of Black's central tasks.
Black attacks the base of White's pawn chain (d4) with ...c5, ...Nc6, and ...Qb6. Later, Black can strike at the head of the chain (e5) with the thematic ...f6 pawn lever.
The Winawer occurs when White plays 3.Nc3 and Black responds with 3...Bb4, pinning the knight. It is one of the sharpest, most combative variations in all of chess opening theory.
The Tarrasch Variation (3.Nd2) develops the knight to d2 rather than c3. It avoids the pin on b4 and keeps the c-pawn mobile to reinforce d4 with c3.
No, after 3.exd5 exd5, the position becomes completely symmetrical and open. It is safe for Black, though White retains a tiny first-move advantage.
World champions Mikhail Botvinnik, Tigran Petrosian, and Anatoly Karpov, as well as Viktor Korchnoi, were legendary exponents of the French Defence.
