French Defence (page 2)
Advance Variation: 3.e5
The main line of the Advance Variation continues 3... c5 4. c3 Nc6 5. Nf3 and then we have a branching point:
5... Qb6, the idea is to increase the pressure on d4 and eventually undermine the White centre. The queen also attacks the b2 square, so White's dark-square bishop cannot easily defend the d4-pawn without losing the b2-pawn. White's most common replies are 6.a3 and 6.Be2. 6. a3 is currently the most important line in the Advance: it prepares 7.b4, gaining space on the queenside. Black may prevent this with 6...c4 intending to take en passant if White plays b4, which creates a closed game where Black fights for control of the b3-square. On the other hand, Black may continue developing with 6...Nh6, intending ...Nf5, which might seem strange as White can double the pawn with Bxh6, but this is actually considered good for Black. Black plays ...Bg7 and ...0-0 and Black's king has adequate defence and White will miss his apparently 'bad' dark-square bishop. 6.Be2 is the other alternative, aiming simply to castle. Once again, a common Black response is 6...Nh6 intending 7...cxd4 8.cxd4 Nf5 attacking d4. When the king's knight reaches f5 from h6, there will be three pieces and a pawn attacking the d4 point while there will only be the Nf3, pawn c3, and Qd1 defending the d4-pawn. As mentioned, White's dark-square bishop cannot come to the rescue because the b2-pawn will fall. Thus, White must plan prophylactically and reply to 6...Nh6 with 7.Na3 preparing to defend the d4-pawn with Nc2.
5... Bd7 was mentioned by Greco as early as 1620, and was revived and popularised by Viktor Korchnoi in the 1970s. Now a main line, the idea behind the move is that since Black usually plays ...Bd7 sooner or later, he plays it right away and waits for White to show his hand. If white plays 6 a3 in response, modern theory says that Black equalises or is better after 6...f6! The lines are complex, but the main point is that a3 is a wasted move if the black queen is not on b6 and so Black uses the extra tempo to attack the white centre immediately.
There are alternative strategies to 3... c5 that were tried in the early 20th century such as 3...b6, intending to fianchetto the bad bishop and which can transpose to Owen's Defence or 3...Nc6, played by Carlos Guimard, intending to keep the bad bishop on c8 or d7 which is passive and obtains little counterplay. Also, 4...Qb6 5 Nf3 Bd7 intending 6...Bb5 to trade off the "bad" queen's bishop is possible.
Tarrasch Variation: 3.Nd2
The Tarrasch Variation is named after Siegbert Tarrasch. This move became particularly popular during the 1970s and early 1980s when Anatoly Karpov used it to great effect. Though more passive than the alternate 3.Nc3, it is still played today by players seeking a small, safe advantage.
Like 3.Nc3, 3.Nd2 protects e4, but is different in several respects: it does not block the path of White's c-pawn, which means he can play c3 at some stage to support the d4-pawn. Hence, it avoids the Winawer Variation because 3...Bb4 lacks the pinning effect, answered readily by 4.c3. On the other hand, 3.Nd2 hems in White's dark-square bishop and it commits White's queen knight to developing to an arguably less active square.

3... c5 4. exd5 and now Black has two ways to recapture:
-
4... exd5 this was a staple of many old Karpov–Korchnoi battles, including seven games in their 1974 match, usually leads to Black having an isolated queen's pawn (see isolated pawn). The main line continues 5. Ngf3 Nc6 6. Bb5 Bd6 7. 0-0 Nge7 8. dxc5 Bxc5 9. Nb3 Bb6 with a position where, if White can neutralise the activity of Black's pieces in the middlegame, he will have a slight advantage in the ending. Another possibility for White is 5.Bb5+ Bd7 (5...Nc6 is also possible) 6.Qe2+ Be7 7.dxc5 to trade off the bishops and make it more difficult for Black to regain the pawn.
-
4... Qxd5 is an important alternative for Black; the idea is to trade his c- and d-pawns for White's d- and e-pawns, leaving Black with an extra centre pawn. This constitutes a slight structural advantage, but in return White gains time for development by harassing Black's queen. This interplay of static and dynamic advantages is the reason why this line has become popular in the last decade. Play usually continues 5. Ngf3 cxd4 6. Bc4 Qd6 7. 0-0 Nf6 (preventing 8.Ne4) 8. Nb3 Nc6 9. Nbxd4 Nxd4, and here White may stay in the middlegame with 10.Nxd4 or offer the trade of queens with 10.Qxd4, with the former far more commonly played today.
-
While the objective of 3...c5 was to break open the centre, 3... Nf6 aims to close it. After 4. e5 Nfd7 5. Bd3 c5 6. c3 Nc6 (6...b6 intends ...Ba6 next to get rid of Black's "bad" light-square bishop, a recurring idea in the French) 7. Ne2 (leaving f3 open for the queen's knight) 7... cxd4 8. cxd4 f6 9. exf6 Nxf6 10. Nf3 Bd6 Black has freed his pieces at the cost of having a backward pawn on e6. White may also choose to preserve his pawn on e5 by playing 4. e5 Nfd7 5. c3 c5 6. f4 Nc6 7. Ndf3, but his development is slowed as a result, and Black will gain dynamic chances if he can open the position to advantage.
-
3... Nc6 is known as the Guimard Variation: after 4.Ngf3 Nf6 5.e5 Nd7 Black will exchange White's cramping e-pawn next move by ...f6. However, Black does not exert any pressure on d4 because he cannot play ...c5, so White should maintain a slight advantage, with 6.Be2 or 6 Nb3.
-
3... Be7, a fashionable line among top GMs in recent years, this odd-looking move aims to prove that every White move now has its drawbacks, e.g. after 4.Ngf3 Nf6 5.e5 Nfd7 White cannot play f4, whereas 4.Bd3 c5 5.dxc5 Nf6 and 4.e5 c5 5. Qg4 Kf8!? lead to obscure complications. Amazingly, 3...h6?!, with a similar rationale, has also gained some adventurous followers in recent years, including GM Alexander Morozevich.
-
Another rare line is 3... a6, which gained some popularity in the 1970s amongst Black players, the idea being to deny White's light-square bishop use of b5 before playing ...c5.
Early deviations for White
After 1.e4 e6, almost 90 percent of all games continue 2.d4 d5, but White can try other ideas. The most important of these is 2.d3 d5 3.Nd2, with a version of the King's Indian Attack. White will likely play Ngf3, g3, Bg2, 0-0, c3 and/or Re1 in some order on the next few moves. Black has several ways to combat this setup: 3...c5 followed by ...Nc6, ...Bd6, ...Nf6 or ...Nge7 and ...0-0 is common, 3...Nf6 4.Ngf3 Nc6 plans ...dxe4 and ...e5 to block in the Bg2, and 3...Nf6 4.Ngf3 b6 makes ...Ba6 possible if White's light-square bishop leaves the a6–f1 diagonal. 2.d3 has been used by many leading players over the years, including GMs Pal Benko, Bobby Fischer and Lev Psakhis.
-
2.Qe2 is the Chigorin Variation, which discourages 2...d5 because after 3.exd5 the black pawn is pinned, meaning Black would need to recapture with the queen. Black usually replies 2...c5, after which play can resemble the 2.d3 variation or the Closed Variation of the Sicilian Defence.
-
2.Nf3 d5 3.Nc3 is the Two Knights Variation: 3...d4 and 3...Nf6 are good replies for Black.
-
2.b3 leads to the Réti Gambit after 2...d5 3.Bb2 dxe4, but Black can also decline it with 3...Nf6 4.e5 Nd7 with White going for f4 and Qg4 before putting the knight on f3.
-
2.e5 is known as the Steinitz Attack, after the first World Champion who analysed and sometimes played it in the late nineteenth century. It is not considered a challenging response to 1...e6 and, as such, is relatively rare.
-
2.Bc4 is rare, to which Black may respond with 2...b6 or 2...d5.[5]
-
After 2.d4 d5 White can also choose the Diemer-Duhm Gambit with 3.c4?!, but this move is considered weak by theory.[6] The most common continuation is 3...dxe4 4. Nc3 Nf6 5. f3, after which 5...Bb4, 5...c5, and 5...exf3 are all possible. Further information can be found on the DDG site.
Early deviations for Black
Although 2...d5 is the most consistent move after 1.e4 e6 2.d4, Black occasionally plays other moves:
-
2...c5 is known as the Franco-Benoni Defence because it features the ...c5 push characteristic of the Benoni Defence after the initial moves of the French. White may continue 3.d5, when play can transpose into the Benoni, though White has extra options since he need not play c4. 3.Nf3, transposing into a normal Sicilian Defence, and 3.c3, transposing into a line of the Alapin Sicilian (usually arrived at after 1.e4 c5 2.c3 e6 3.d4) are also common. Play may also lead back to the French; for example, 1.e4 e6 2.d4 c5 3.c3 d5 4.e5 transposes into the Advance Variation of the French Defence.
-
2...f5?! is the Kingston Defence, which shares some characteristics of the Dutch Defence. 3.e5 poses few problems for Black after 3...Ne7 4.Nf3 c5. The biggest test for Black is the Exchange Variation (3.exf5 exf5 4.Bd3) when 4...Nc6 5.Bxf5 Qf6 initiates complex tactics.
-
2...Nf6 is known as the Mediterranean Defence, and is very rare.
History
The French Defence is named after a match played by correspondence between the cities of London and Paris in 1834 (although earlier examples of games with the opening do exist). It was Chamouillet, one of the players of the Paris team, who convinced the others to adopt this defence.[7]
As a reply to 1.e4, the French Defence received relatively little attention in the nineteenth century compared to 1...e5. The first world chess champion Wilhelm Steinitz said "I have never in my life played the French Defence, which is the dullest of all openings".[8] In the early 20th century, Géza Maróczy was perhaps the first world-class player to make it his primary weapon against 1.e4. For a long time, it was the third most popular reply to 1.e4, behind only 1...c5 and 1...e5. However, according to the Mega Database 2007, in 2006, 1...e6 was second only to the Sicilian in popularity.
Historically important contributors to the theory of the defence include Mikhail Botvinnik, Viktor Korchnoi, Aron Nimzowitsch, Tigran Petrosian, Lev Psakhis, Wolfgang Uhlmann and Rafael Vaganian. More recently, its leading practitioners include Evgeny Bareev, Alexey Dreev, Mikhail Gurevich, Alexander Khalifman, Smbat Lputian, Alexander Morozevich, Teimour Radjabov, Nigel Short, Gata Kamsky, and Yury Shulman.
The Exchange Variation was recommended by Howard Staunton in the 19th century,[9] but has been in decline ever since. In the early 1990s Garry Kasparov briefly experimented with it before switching to 3.Nc3. Note that Black's game is made much easier as his queen's bishop has been liberated. It has the reputation of giving immediate equality to Black, due to the symmetrical pawn structure.
Like the Exchange, the Advance Variation was frequently played in the early days of the French Defence. Aron Nimzowitsch believed it to be White's best choice and enriched its theory with many interesting ideas. However, the Advance declined in popularity throughout most of the 20th century until it was revived in the 1980s by GM and prominent opening theoretician Evgeny Sveshnikov, who continues to be a leading expert in this line. In recent years, it has become nearly as popular as 3.Nd2; GM Alexander Grischuk has championed it successfully at the highest levels. It is also a popular choice at the club level due to the availability of a simple, straightforward plan involving attacking chances and extra space.
