1. Bishop for structure
After 4.e5 c5 5.a3 Bxc3+ 6.bxc3, Black gives up the dark-squared bishop and damages White’s queenside pawns. White gains the bishop pair and more space. Black gains clear targets on c3 and d4.
This is not a free win of a pawn structure. White’s centre and bishops can support a dangerous kingside attack. Black must attack the pawn chain quickly enough that White cannot use the extra space without consequences.
2. Attack c3 and d4
The c3-pawn is difficult to defend with another pawn, and d4 remains the base of White’s central chain. Black can use …Qc7, …Ne7 and pressure along the c-file. A later …b6 and …Ba6 may exchange White’s useful light-squared bishop.
Do not rush to win c3 if it opens lines for White’s bishops. First complete development and make sure the queen and king are not exposed. A fixed weakness is useful because it will still be there later.
3. White may attack immediately
White often uses Qg4 to attack g7 and put pressure on the kingside before Black castles. Black may defend with …Kf8 in some theoretical lines, play …Qc7 to counterattack, or use …Ne7 and …Rg8 in sharp positions. These choices are concrete and move-order sensitive.
For a practical repertoire, remember the warning rather than every branch: after Qg4, stop and calculate. Check g7, your king’s escape squares and White’s forcing moves before pursuing queenside material.
4. A useful Black setup
The g8-knight normally belongs on e7, where it does not block the c-pawn and can support c8, f5 or g6. The queen often goes to c7, attacking e5 or c3. The c8-bishop may use d7 or a6 after …b6.
The queenside rook can occupy c8 once the c-file opens. The other rook may use g8 in sharp lines. Black’s plan is not only to survive White’s attack: create enough pressure against the centre and queenside that White must also defend.
5. A sharp position demands calculation
Example board: after White attacks g7
Study the position before revealing the explanation. Material is less important than king safety and forcing moves.
Finish the course with one sentence
Explain the French Defence in your own words. A strong answer sounds like this: “Black builds with …e6 and …d5, attacks White’s centre with …c5, prepares …f6 when safe, and gives the c8-bishop a future.”
In your next French game, pause after development and name three things aloud: White’s pawn-chain base, your least active piece and the pawn break you are preparing. That habit matters more than remembering a long line.
