French Defense Tarrasch Open Chistyakov Defense
French Defense
Definition
The French Defense is a chess opening that begins with the moves 1.e4 e6. Black’s second move will almost always be 2…d5, immediately challenging White’s pawn on e4. The opening is renowned for creating an asymmetrical pawn structure in which Black accepts a spatial disadvantage in the center in return for a solid, resilient position and chances for a later counter-attack against White’s pawn chain.
Typical Usage in Play
- After 1.e4 e6 2.d4 d5, Black attacks the e4-pawn, forcing White to decide how to maintain or relinquish the center (Advance 3.e5, Exchange 3.exd5, Tarrasch 3.Nd2, Classical 3.Nc3).
- Black’s light-squared bishop is often temporarily “imprisoned” behind the e6-d5 pawn chain, so finding a good way to activate it is a recurring strategic theme.
- The French is popular at every level—from club play to world-championship matches—because its structures are clearly defined and rich in middlegame plans.
Strategic & Historical Significance
Thanks to its solid reputation, the French has served as a mainstay for many classical players (Botvinnik, Petrosian, Korchnoi) and even modern champions such as Carlsen and Caruana on occasion. It first appeared in serious competition after a correspondence match between the cities of London and Paris (1834), where the Paris team replied 1…e6—hence “French.”
Example Lines
- Winawer: 1.e4 e6 2.d4 d5 3.Nc3 Bb4
- Classical: 1.e4 e6 2.d4 d5 3.Nc3 Nf6
- Tarrasch: 1.e4 e6 2.d4 d5 3.Nd2 (focus of the next entry)
Interesting Facts
- Despite its “solid” image, the French often produces sharp opposite-side castling attacks (particularly in the Winawer Poisoned-Pawn line).
- Both Kasparov and Fischer, generally 1.e4 players, used the French as Black at critical moments—evidence of its reliability.
- The longest recorded over-the-board game (269 moves, Nikolić–Arsović, Belgrade 1989) started as a French Defense!
Tarrasch Variation (of the French)
Definition
The Tarrasch Variation arises after 1.e4 e6 2.d4 d5 3.Nd2. With 3.Nd2, White supports e4 and avoids the pin …Bb4 that occurs in the Winawer. The line is named after Dr. Siegbert Tarrasch, a leading theoretician of the late 19th and early 20th centuries.
Main Ideas & Usage
- By choosing Nd2 instead of Nc3, White keeps the c-pawn free to advance later (c4 or c3) and retains flexibility against …c5 breaks.
- Black usually replies 3…c5 (Rubinstein), 3…Nf6 (leading to Closed or Open Systems), or the dynamic 3…Nc6 (Guimard).
- The Tarrasch tends to produce IQP (isolated queen’s-pawn) structures or a mobile e5-d4 pawn chain, offering chances for both sides.
Strategic Significance
The variation has been a favorite of world champions such as Anatoly Karpov (as White) and challengers like Viktor Korchnoi (as Black). Its reputation for being “safer” than the Winawer without yielding equality has kept it at the forefront of opening theory for over 100 years.
Illustrative Game
Karpov–Korchnoi, Candidates Final 1974:
1.e4 e6 2.d4 d5 3.Nd2 c5 4.exd5 exd5 5.Ngf3 Nc6 6.Bb5 Bd6 7.dxc5 Bxc5—showing the IQP positions typical of the line.
Open System (within the French Tarrasch)
Definition
After 3…Nf6 4.e5 Nfd7 in the Tarrasch, play can branch into the Closed System (where the central tension remains) or the Open System. The Open System comes about when Black exchanges pawns on d4 with …c5 …cxd4, opening the center:
1.e4 e6 2.d4 d5 3.Nd2 Nf6 4.e5 Nfd7 5.Bd3 c5 6.c3 Nc6 7.Nf3 cxd4 8.cxd4.
How It Is Used
- Black uses …c5 and …cxd4 to undermine White’s powerful e5 pawn and acquire counter-play on the half-open c-file.
- White, enjoying extra space, aims for a kingside initiative (often f4–f5) while keeping an eye on the newly isolated d4-pawn.
Strategic Significance
The Open System leads to dynamic, unbalanced middlegames featuring hanging pawns (c5/d5 or c4/d4) or IQP structures—perfect terrain for players seeking complexity.
Famous Example
Kasparov–Short, Paris Rapid 1990 followed the Open line, culminating in a spectacular rook sacrifice by Kasparov to exploit Black’s lagging development.
Chistyakov Defense (C07)
Definition
The Chistyakov Defense is a sub-variation of the Open System in the French Tarrasch, characterized by Black’s early queen sortie to b6:
1.e4 e6 2.d4 d5 3.Nd2 Nf6 4.e5 Nfd7 5.Bd3 c5 6.c3 Nc6 7.Ne2 cxd4 8.cxd4 Qb6.
It is named after the Russian master Alexander Chistyakov, who analyzed the line extensively in the mid-20th century.
Key Ideas & Plans
- Pressure on d4 and b2: The queen simultaneously attacks the d4-pawn (already isolated) and the b2-pawn, forcing White to make concessions in development or structure.
- Rapid activity: Black often follows up with …f6 or …Be7 and 0-0, aiming to strike at the e5 stronghold while keeping the queen active on the queenside.
- Flexible pawn breaks: Later …f6, …g5, or …f5 can appear, depending on how White arranges his pieces.
Model Game
Timman – Yusupov, Tilburg 1992 illustrates typical play: Black equalized comfortably and later seized the initiative on the kingside thanks to well-timed …f6 and …g5 thrusts.

Interesting Facts & Anecdotes
- Because the queen comes out so early, many thought the line was unsound. Modern engines, however, show it to be fully playable, reviving interest among theory buffs.
- Alexander Morozevich successfully employed the Chistyakov in the 2000s, adding many fresh tactical resources to Black’s arsenal.
- The ECO code for the line is C07, falling neatly under “French Defense, Tarrasch Variation, Open System, Chistyakov Defense.”
