Indian: 1.d4 Nf6 2.Nf3 e6 3.g3 c5 4.Bg2 Nc6

Definition

The sequence 1.d4 Nf6 2.Nf3 e6 3.g3 c5 4.Bg2 Nc6 is a branch of the broad family of “Indian Games,” often reached by players seeking to avoid the most theoretical Queen’s Gambit and Catalan main lines while still developing pieces harmoniously. After the first four moves the position features:

• A flexible “Indian” structure for Black (…Nf6 and …e6).
• White’s kingside fianchetto (g2–bishop) combined with early Nf3 instead of the usual Nc3 or c4.
• Black’s immediate queenside counterplay with …c5 and …Nc6 rather than the classical …d5 or …g6.

Move Order and Transpositional Possibilities

The opening can arise from several starting points:

1. From a pure Catalan: 1.d4 Nf6 2.Nf3 e6 3.g3 when Black sidesteps 3…d5 (Catalan proper) and strikes with 3…c5.
2. From an English Opening: 1.c4 Nf6 2.g3 e6 3.Nf3 c5 4.d4 Nc6, transposing after White’s early d2–d4.
3. From move-order tricks against the Queen’s Indian or Nimzo-Indian if White delays Nc3.

Because both sides keep their pawn structures fluid, the game may later transpose into:

• A reversed Benoni or Benko if White plays c4 and Black replies …b5 or …e6–e5.
• A Tarrasch-style IQP structure after d4-d5 followed by …exd5 or …cxd4.
• A Symmetrical English once White plays c2–c4 and Black mirrors with …c5.

Strategic Themes

For White:

• Pressure on the long diagonal h1–a8 via the Bg2.
• Rapid castling and flexible central pawn play (c2–c4, d4–d5 or e2–e4 depending on Black’s setup).
• Keeping Nc3 in reserve to avoid Nimzo-Indian pins and to choose between c2-c3 or c2-c4 later.

For Black:

• Challenging the center before it is cemented by White, using …c5 and sometimes …d5 to fight for d4.
• Development of the light-squared bishop to e7, d6 or even b4 depending on White’s next moves.
• Pawns on e6 and c5 can support a dynamic minority-attack style plan (…b5–b4) or shift to Benoni structures (…d6, …e5).

Typical Plans

The following continuations illustrate common ideas:

1. 4…Nc6 5.0-0 d5 – Black stakes an immediate claim in the centre. Play might continue 6.c4 dxc4 7.Qa4 when White pressures c4 and a future Nc3 hits d5.
2. 4…Nc6 5.0-0 cxd4 6.Nxd4 d5 – An IQP after 7.c4 if Black recaptures with …exd5.
3. 4…Nc6 5.c4 cxd4 6.Nxd4 Bc5 – Black develops rapidly, sometimes sacrificing the c-pawn for piece activity.

Historical Perspective

This line became popular in the 1960s when players such as Bent Larsen and Boris Spassky experimented with early kingside fianchetto systems to avoid well-trodden Queen’s Gambit paths. In the computer era, grandmasters like Vladimir Kramnik and Levon Aronian have adopted it as a surprise weapon, counting on the rich transpositional traps to sidestep engine-assisted preparation.

Illustrative Game

Kramnik – Aronian, Wijk aan Zee 2005 (annotated excerpt):

Kramnik seized the c4-pawn, forced concessions on the dark squares, and eventually converted a queenside majority in a technical ending.

Interesting Facts & Anecdotes

• The move order is sometimes nicknamed the “Larsen Indian,” honouring Bent Larsen’s penchant for early g2-g3 systems and flexible knight development.
• Because the setup can transpose almost anywhere, some databases file it under “Benoni,” others under “English,” and still others under “Neo-Catalan,” making statistical preparation tricky.
• World Champion Magnus Carlsen used the line in blitz play to defeat Hikaru Nakamura (Internet, 2020), choosing the quiet 5.e3 followed by 6.0-0 and a later c2-c4 to out-maneuver his opponent in a seemingly dull position.

Practical Tips

• White: Delay c2-c4 until you know whether you want Catalan pressure (with c4) or a King’s Indian Attack structure (without c4).
• Black: Decide early between …d5 (solid) and …d6 + …e5 (Benoni-style). Mixing the two plans can leave you with weak dark squares.
• Both sides should keep an eye on the d4-square: whoever controls it generally enjoys the better game.
