English: Anglo-Indian, 2.Nc3 g6
Definition
The English Opening: Anglo-Indian, 2.Nc3 g6 arises after 1. c4 Nf6 2. Nc3 g6. It is a flexible, hypermodern setup where Black prepares to fianchetto the king’s bishop to g7, challenging White’s center from a distance. This move order belongs to the English Opening family and commonly heads toward “colors reversed” King’s Indian or Grünfeld structures.
In ECO classification, this line is cataloged within A16–A19: English Opening, Anglo-Indian variations with ...g6.
Core Idea and Usage
How it is used in chess
By playing 2...g6, Black adopts a hypermodern stance: instead of occupying the center immediately, Black aims to counterattack it with pawn breaks like ...e5, ...c5, or ...d5 after castling and development. White, enjoying the first move, can choose from a variety of setups—ranging from quiet fianchetto systems to direct central grabs that transpose to mainline King’s Indian or Grünfeld positions.
- Reversed King’s Indian: 1. c4 Nf6 2. Nc3 g6 3. g3 Bg7 4. Bg2 0-0 5. Nf3 d6 6. 0-0 e5 leads to a King’s Indian structure with colors reversed and an extra tempo for White.
- Transposing to the King’s Indian Defense: 1. c4 Nf6 2. Nc3 g6 3. e4 d6 4. d4 gives a standard KID position (same structure as 1. d4 Nf6 2. c4 g6 3. Nc3 Bg7 4. e4 d6).
- Transposing to the Grünfeld Defense: 1. c4 Nf6 2. Nc3 g6 3. d4 d5! followed by ...Bg7 and ...c5 often reaches mainline Grünfeld territory.
Because of these rich transpositional possibilities, the Anglo-Indian with 2...g6 is a favorite of players who want to steer the game toward familiar Indian-Defense themes without allowing White to dictate the exact flavor too early. See also: Transposition, Colors reversed, Fianchetto, ECO.
Strategic Themes
Plans for White
- Reversed KID Squeeze: Adopt a “slow burn” setup with g3, Bg2, Nf3, 0-0, d3, Rb1, a3, b4. Use the extra tempo to restrain Black’s ...e5/...f5 and expand on the queenside.
- Central Expansion: Play e4 and d4 quickly to transpose to the KID or Grünfeld as desired. The extra move can offer a tangible space advantage and earlier pressure.
- Botvinnik Setup: c4, g3, Bg2, e4, Nge2, d3, f4—clamps dark squares and prepares a kingside space gain. See also: Botvinnik.
- Key breaks: d4 (when ready), b4-b5 on the queenside, or f4 in Botvinnik structures; always time the breaks to avoid tactical counters.
Plans for Black
- Countercenter with ...e5 or ...c5: Challenge White’s space and aim for piece activity on the long diagonal g7–a1.
- Grünfeld Approach with ...d5: Strike at d4 immediately when White commits the central pawn, leading to open, dynamic play.
- Modern/KID Structures: ...d6, ...Nbd7, ...e5, ...Re8, and sometimes ...a6, ...Rb8, ...b5 against queenside plans; prepare ...f5 in true KID fashion if the position calls for it.
- Piece Placement: Knights often head to c6 and d7 (or e5/c5 outposts after pawn breaks). The bishop on g7 is the pride of Black’s setup; avoid shutting it in with premature ...e6 unless justified.
Typical Move Orders and Transpositions
Main Reversed KID Path
White opts for a safe kingside fianchetto, aiming for a solid bind and queenside expansion.
Sample line:
Ideas: White watches the central dark squares (e4, d5, f5) and keeps d3–d4 in reserve. Black eyes ...f5 or ...d5 and queenside expansion with ...a5–...a4.
Grünfeld Transposition
Dynamic central play arises quickly if White plays d4 and Black answers with ...d5.
Sample line:
Here, White often aims for a space advantage with e4 and a strong center; Black counters with piece activity against d4/c4 and pressure on the long diagonal.
Direct KID Transposition
If White wants mainline King’s Indian theory, this route does it immediately:
White’s extra tempo from the English move order can make certain KID lines less comfortable for Black if unprepared.
Strategic and Historical Significance
Why it matters
The Anglo-Indian with 2...g6 is a cornerstone of English Opening strategy, bridging multiple top-tier defenses in one repertoire. It embodies the hypermodern credo—control the center with pieces and timely pawn breaks. Many elite players (e.g., Carlsen, Kramnik, Anand, Giri) have used it from both sides to steer games into familiar structures with rich middlegame play.
- Flexibility: White can choose between a slow squeeze or direct central occupation; Black can aim for KID, Grünfeld, or Modern-style play.
- Theory depth: Because of transpositions, studying plans and pawn structures is often more fruitful than memorizing long forcing lines—an excellent training ground for understanding over rote Book moves.
- Engine era resilience: Current Engines often rate these positions as roughly equal with a small pull for White due to the tempo, but practical chances abound for both sides.
Typical Plans, Tricks, and Pitfalls
For White
- Don’t rush d4 if your pieces aren’t ready; premature central expansion can invite a well-timed ...c5 or ...e5 break with counterplay.
- Queenside advance: Rb1, b4, b5 is a common space-gaining idea in the reversed KID. Time it against Black’s ...a5 or ...c6/...a5 setups.
- In Botvinnik setups, watch the dark squares: avoid loosening the e4–f4 complex without support.
For Black
- Be consistent: If you choose a KID plan (...d6, ...e5), commit your pieces accordingly; if Grünfeld (...d5) is your choice, act fast to hit White’s center.
- Guard the g7–bishop: It’s your most important piece; avoid locking it behind ...e6 unless a concrete line justifies it.
- Typical counterplay: ...c6 and ...a6–...b5 against queenside expansions; ...f5 breaks in KID structures when White’s center is fixed.
Mini “Gotcha”
Move-order nuances matter. After 1. c4 Nf6 2. Nc3 g6 3. e4, Black should be ready for 4. d4 and precise KID/Grünfeld theory. Casual moves can lead to a quick space disadvantage or tactical shots on e5/d5 squares—classic Trap territory for the unprepared.
Examples You Can Play Through
Quick, instructive model (reversed KID)
Focus on the long diagonal, kingside light squares, and a slow queenside push.
White’s plan is steady improvement followed by a well-timed d3–d4 or b2–b4 break; Black eyes ...f5 or queenside counterplay.
Interesting Facts and Anecdotes
Did you know?
- The name “Anglo-Indian” reflects English Opening move orders leading to Indian Defense structures—an early nod to the importance of transpositions in modern opening play.
- Many “English” games end up being King’s Indian or Grünfeld battles with subtle move-order twists; strong players exploit this to sidestep opponent preparation (“Home prep”).
- Because the positions are strategically rich rather than forced, they are popular in Rapid and Blitz where understanding plans beats deep memorization.

Practical Checklist
White
- Decide early: KID/Grünfeld transposition (e4/d4) or a reversed KID squeeze (g3/Bg2/d3/Rb1/a3/b4)?
- Provoke ...e5 or ...c5, then target the resulting weak squares (d5, d6, or d4).
- Keep an eye on the g2–b7 diagonal; tactical themes often revolve around that line.
Black
- Pick your plan: ...d5 (Grünfeld), ...e5 (KID/Modern), or ...c5 (English/Symmetrical ideas) and harmonize your piece placement.
- Use timely pawn breaks to undermine White’s center—don’t drift into passivity.
- In reversed KID structures, consider ...a5–...a4 or ...b5 to challenge queenside space.

Summary
The English: Anglo-Indian, 2.Nc3 g6 is a highly flexible way to reach world-class structures. White can play for a small, stable edge by leveraging the extra tempo in reversed KID setups, or dive into mainstream KID/Grünfeld theory with e4/d4. Black, in turn, chooses the counterattacking scheme—...d5, ...e5, or ...c5—that best suits their style. Understanding typical plans and pawn breaks matters more than memorizing long forcing lines.
