Caro-Kann Defense
The solid answer to 1.e4 that keeps the light-squared bishop free. Think of it as the French Defense without the bad bishop.
Sicilian Defense
The most analyzed answer to 1.e4, and the most popular one at master level. Black declines a symmetrical fight and plays for a win from move one.
Scandinavian Defense
Challenge the center on move one. The theory is light, the plans are clear, and the 2...Qxd5 lines keep reaching the same pawn structure.
The idea behind 1...e6
Black prepares ...d5 with a pawn behind it. After 2.d4 d5 White's e4 pawn is attacked, so White has to advance it with e5, defend it with Nc3 or Nd2, or trade on d5. Each choice leads to a well-known structure, and both sides know what they are aiming at.
The famous drawback is the light-squared bishop on c8, locked in by its own pawn on e6. Many French plans are ways of solving that bishop: ...b6 and ...Ba6, ...Bd7-b5, or freeing it by exchanging on d4 and playing ...f6.
Main variations
The five lines you need to know, and the plan in each:
- Advance (3.e5): the pawn chain d4/e5 versus d5/e6 is fixed. Black attacks the base of White's chain with ...c5 and piles up on d4: ...Nc6, ...Qb6, ...Nh6-f5. White defends d4 and looks for a kingside attack.
- Tarrasch (3.Nd2): White keeps the option of c3 and avoids the Winawer pin. Black replies 3...c5, which often leads to an isolated-queen-pawn game, or 3...Nf6, which closes the center.
- Winawer (3.Nc3 Bb4): Black pins the knight and usually trades it, giving White doubled c-pawns and the bishop pair. The play is very sharp, with White attacking on the kingside while Black goes after the queenside and the weak c-pawns.
- Classical (3.Nc3 Nf6): a calmer development than the Winawer. 4.Bg5 and 4.e5 both lead to well-mapped middlegames.
- Exchange (3.exd5): symmetrical and quiet. Black has nothing to fear here. Aim for better piece placement and be ready for a long game.
The most useful habit in the French is to ask, before every move, whether ...c5 is possible and whether it is good. Many French mistakes come from developing the pieces while the ...c5 break stops working.
Common mistakes at club level
- Playing ...c5 too late, after White has consolidated d4 with c3, Nf3 and Be3.
- Trading the dark-squared bishop for no reason and then finding the dark squares around the king indefensible.
- Forgetting the c8-bishop entirely, and reaching an endgame a piece down in practical terms.
- In the Advance, grabbing on d4 too early and opening lines for White's better-developed pieces.
Frequently asked questions
Is the French Defense good for beginners?
Yes. The pawn structures repeat, so the plans transfer from game to game, and there is far less forced theory than in the Sicilian. The one thing to accept early is that the c8-bishop is often passive for a while.
How do I beat the Advance Variation?
Attack the base of the chain. Play ...c5 quickly, add pressure with ...Nc6 and ...Qb6 against d4, and route the king's knight via h6 to f5 where it hits d4 and e3. If White defends d4 successfully, look for ...f6 to hit the head of the chain instead.
What is the bad bishop in the French?
The light-squared bishop on c8. Black's pawns on e6 and d5 sit on light squares, blocking its diagonals. Freeing it or trading it, with ...b6 and ...Ba6, ...Bd7-b5 or an eventual ...f6, is a recurring theme in most French middlegames.
