Nimzo-Indian Botvinnik: 7...dxc4 8.Bxc4 c5 9.Ne2
Nimzo-Indian: Botvinnik, 7…dxc4 8.Bxc4 c5 9.Ne2
Definition
The “Botvinnik Variation” of the Nimzo-Indian Defence refers to the sequence that typically arises after:
1. d4 Nf6 2. c4 e6 3. Nc3 Bb4 4. e3 c5 5. Bd3 Nc6 6. Nf3 Bxc3+ 7. bxc3 dxc4 8. Bxc4 c5 9. Ne2
The line is named for former World Champion Mikhail Botvinnik, who championed the structure in the 1940s-50s. After Black captures on c4 (7…dxc4), White recaptures with the bishop and immediately stabilises the center with 9.Ne2, intending f2–f3 and e3–e4. The variation offers White the bishop pair and a broad pawn center, while Black strives for counterplay against the dark squares and the c-file.
Typical Move Order
The most common route is:
- 1. d4 Nf6
- 2. c4 e6
- 3. Nc3 Bb4
- 4. e3 c5
- 5. Bd3 Nc6
- 6. Nf3 Bxc3+
- 7. bxc3 dxc4
- 8. Bxc4 c5
- 9. Ne2 …
After 9.Ne2 White’s immediate threats are minimal, but the knight supports central expansion with e3-e4 and guards the d4-square. Black has several replies, the main ones being 9…0-0, 9…Qc7, or 9…Na5.
Strategic Themes
- The Bishop Pair: White voluntarily accepts doubled c-pawns to keep both bishops. The long-term goal is to open the position with e3-e4 or d4-d5 so the bishops can dominate.
- Pawn Structure: White’s pawns often sit on c3-d4-e3-f2, resembling an extended Carlsbad structure. Black’s pieces pressure the c4 and d4 squares, sometimes prompting …b6 and …Ba6.
- Central Breaks: White prepares f2-f3 followed by e3-e4. Black counters with …e5, …cxd4, or …b5 to dissolve the center before it becomes dangerous.
- Piece Placement: The knight on e2 may reroute to g3 or f4, while the queen often goes to e2. Black’s typical minor-piece manoeuvre is …Bd7-c6 or …Na5-c4.
Historical Significance
Mikhail Botvinnik unveiled the line in training games during the 1930s and used it in several high-profile encounters after World War II. His systematic approach—emphasising strategic principles over immediate tactics—made the variation popular among Soviet players. Although less fashionable today than the Rubinstein (4.e3 without 5.Bd3) or Classical (4.Qc2) systems, the Botvinnik line remains a sound, ambitious choice.
Illustrative Games
- Botvinnik – Keres, Moscow 1948 (World Championship) White unleashed a textbook central break with 19.e4! and demonstrated the power of the bishop pair.
- Kramnik – Lékó, Brissago 2004 (WCh Match, Game 2) Kramnik employed a modern move order, revealing new ways to handle Black’s …Na5 plan.
- Caruana – Mamedyarov, Shamkir 2014 A well-prepared Caruana sacrificed a pawn for long-term pressure, showing the line’s theoretical vitality.

Practical Tips
- Remember the move-order trap: 9…e5? 10.d5! forces Black’s knight to an awkward square and gives White a lasting space advantage.
- If Black plays 9…Na5 immediately, do not retreat 10.Bd3?—instead consider 10.Bd3 (yes, it stays), meeting 10…cxd4 with 11.cxd4 to keep the center intact.
- After 9…0-0 10.0-0 e5, the thematic pawn sacrifice 11.d5! can lead to rich middlegames; study Botvinnik’s games for guidance.
Interesting Facts & Anecdotes
- Botvinnik reportedly developed the line while analysing alone in a train compartment, inspired by Nimzowitsch’s ideas of central control versus piece activity.
- Because the variation often leads to a Maróczy-style bind, some contemporary authors nicknamed it “The Nimzo-Maróczy.” The moniker never stuck, but it highlights the structural similarity.
- World Champion Magnus Carlsen experimented with the Botvinnik setup in blitz and online rapid events—even against the computer engine “Sese” during training sessions.
