The plan, from masters' games

The strong players' line runs 2. 3. 4. 5. . It leads to the structure the French is built around: your opponent closes the centre with a d4–e5 pawn chain, and you go after its base, d4, with your c-pawn. If d4 falls or gets traded, e5 loses the pawn holding it up.

sets up , so your d-pawn lands with support and challenges e4 straight away. The cost is your c8 bishop: with pawns on e6 and d5 it can only reach d7, boxed in behind your pawns. That is why your play belongs on the queenside, where you can manage without it.

3. defends e4. attacks it a second time, with the d5 pawn and the knight, and forces your opponent to settle the tension. 4. grabs space and kicks the knight. The retreat is not a random one: from d7 the knight eyes e5 and covers c5, the square your break needs. 5. puts a second pawn behind e5. Then comes , the choice of 96 strong players in 100. It hits d4, which at that moment only the queen on d1 defends.

Move order matters here. The knight comes out before the c-pawn because an immediate opens the centre with your king still on e8. The mistakes section shows how that goes wrong.

The same idea holds when your opponent closes things earlier with 3.. In that structure, 97 strong players in 100 attack the base of the chain with the c-pawn, and 14 in 100 online turn to the f-pawn against e5.

At your level the line tends to drift early. After , only 29 opponents in 100 play 5., against 76 in 100 strong players. Without that pawn, e5 has one less pawn behind it, and your strike at d4 stays exactly the same.

The mistakes that cost the most games

Mistake

A mistake. After 3., opens the centre with your king on e8. Play goes 4. 5. 6. : the e-file is open and both your bishops are pinned to the king. If 7. follows, the e7 bishop cannot take back. Play . At your level 26 in 100 play it, and you score 46.7 against 50.6.

26 in 100 play it in this position. It gives away 1.3 pawns of advantage. It scores 46.7%; scores 50.6%.

Inaccuracy

An inaccuracy that rarely gets punished at your level. After 2., holds back the d-pawn and leaves c6 without the b7 pawn guarding it. In the line 3. 4. 5. , the e5 knight eyes c6 and you spend a tempo keeping the enemy bishop off b5. Play . You score 49.5 against 50.8.

6 in 100 play it in this position. It gives away 0.8 pawns of advantage. It scores 49.5%; scores 50.8%.

Inaccuracy

An inaccuracy that barely gets punished at your level. After 2., moves the d-pawn just one square. In the line 3. 4. 5. it ends up on d5 anyway, so you reach the French structure a tempo down. Play right away. You score 49 against 50.8.

6 in 100 play it in this position. It gives away 0.7 pawns of advantage. It scores 49.0%; scores 50.8%.

Inaccuracy

An inaccuracy that makes almost no difference at your level: you score 50.1 against 50.8. After 2., commits the c-pawn too early. In the line 3. 4. 5. your opponent already has the d4–e5 chain, and that pawn needs another move to reach c5. Play .

6 in 100 play it in this position. It gives away 0.7 pawns of advantage. It scores 50.1%; scores 50.8%.

Inaccuracy

An inaccuracy, but an expensive one. After 3., parks the knight in front of your c-pawn, which can no longer reach c5 to hit d4. In the line 4. 5. 6. you have to go after e5 instead. Play . At your level 11 in 100 players choose it, and you score 45.4 against 53.4.

11 in 100 play it in this position. It gives away 0.7 pawns of advantage. It scores 45.4%; scores 53.4%.

Mistake

A mistake, though at your level it rarely gets punished. After 2., brings the queen out before any minor piece. Then 3. 4. : the c3 knight guards e4, which your queen was hitting, the f3 knight chases her, and she goes home with two enemy knights already out. Play . You score 48.7 against 50.5.

2 in 100 play it in this position. It gives away 1.2 pawns of advantage. It scores 48.7%; scores 50.5%.

Questions

What is the French Defense?

It is the reply to 1., followed by . Your e6 pawn props up d5 but shuts in your c8 bishop, so your play is on the queenside, where your c-pawn attacks d4. It shows up in 6 games out of 100 between 900 and 1700, and over the board above 2300, strong players with Black score 40 in 100.

Is the French Defense good for beginners?

It works, because the plan keeps repeating: a d4–e5 chain, and your c-pawn hitting its base. At your level the most common line is 3., played by 49 opponents in 100, and there you score 52 in 100. The danger lies in your own moves: 26 players in 100 answer 3. with , which is a mistake.

What are the main ideas in the French Defense?

Hit d4 with your c-pawn once the centre is closed. Against 3., that means straight away. Against 3., develop first with , and after 4. the knight covers c5 for the break. After 3., take back with and your c8 bishop is free.
