English: Symmetrical, 2...b6
English: Symmetrical
Definition
The term “English: Symmetrical” refers to the family of positions that arise after the moves 1. c4 c5 in the English Opening. Both sides place a pawn on the c-file, creating a completely symmetrical pawn structure in the center and on the wings. Although the position looks balanced, the struggle for the initiative begins immediately through piece development, pawn breaks such as …d5 or d4, and subtle move-order nuances.
How It Is Used in Chess
- Opening Classification: Encyclopaedia of Chess Openings (ECO) codes C4–C12 cover the main Symmetrical English variations.
- Strategic Shorthand: Players and writers will say, “She played a Symmetrical English” as a concise way to describe the first-move sequence 1. c4 c5.
- Transpositional Tool: The Symmetrical English can transpose into the Tarrasch Defence, Hedgehog systems, or even certain Queen’s Gambit Declined structures after moves like d4 …d5.
Strategic Themes
- Minor-Piece Placement: Because no central pawns are exchanged immediately, piece activity—especially the positioning of the kingside knight (f3 vs f6) and fianchettoed bishops—often dictates the battle.
- Breaks with d4 / …d5: One side will generally try to seize the center by advancing the d-pawn, aiming either to open lines or create an isolated d-pawn in the opponent’s camp.
- Hedgehog Structures: If Black delays …d5 and instead adopts a setup with …e6, …b6, …g6, and pawns on the 6th rank, the tense Hedgehog appears—rich in counter-punching possibilities.
- Move-Order Traps: Because both sides often postpone d-pawn advances, inaccurate development (e.g., 4…d5? when pieces are awkward) can cede the initiative or lose material outright.
Historical Significance
The Symmetrical English became popular in the 1970s as players such as Anatoly Karpov and Ulf Andersson demonstrated its flexibility and solidity. Later, Garry Kasparov, Magnus Carlsen, and Ding Liren all incorporated it into their repertoires, using its transpositional nature to dodge deep preparation in 1. d4 openings.

Carlsen – Anand, World Championship (Game 5), Sochi 2014
Carlsen employed the Symmetrical English to sidestep Anand’s preparation. The game later transposed into a Queen’s Gambit Declined structure, culminating in a technical grind that the Norwegian eventually converted.
Interesting Facts
- Because both sides keep their e- and d-pawns at home for several moves, the Symmetrical English often lasts 8–10 moves before a single central pawn is exchanged.
- Grandmasters sometimes choose the Symmetrical English specifically on “must-draw” occasions, yet its latent complexity has produced numerous decisive results at elite level.
2...b6
Definition
“2…b6” is a descriptive shorthand for any opening line in which Black’s second move is the pawn advance to b6, preparing to fianchetto the queen’s bishop on b7. While the exact position depends on White’s first two moves, the common aim is to exert long-diagonal pressure (b7–g2 or b7–e4) early in the game.
Typical Opening Families Featuring 2…b6
- Queen’s Indian Defence: 1. d4 Nf6 2. c4 b6 (ECO A45–A49)
- Sicilian Defence, Nimzo-Larsen Variation: 1. e4 c5 2. Nf3 b6
- Owen-style Lines vs. 1. e4 e5: 1. e4 e5 2. Nf3 b6 (rare but tricky)
Strategic Ideas
- Fianchetto Pressure: By playing …b6 and …Bb7 quickly, Black eyes the e4-square (against 1. d4) or the g2-square (against 1. e4), creating latent tactics on the long diagonal.
- Flexible Center: Black often delays committing the d- and e-pawns, keeping options open for …d5, …e6, or even …g6 depending on White’s setup.
- Minor-Piece Coordination: The fianchettoed bishop combines effectively with a knight on f6 and sometimes a later …c5 pawn thrust to challenge White’s central pawns.
Historical Context
The idea of an early …b6 gained traction in the late 19th century with Johannes Zukertort and was systematized in the Queen’s Indian Defence by the Maróczy–Capablanca era. In the 1970s, Bent Larsen experimented with 1. b3 (the reverse of …b6) and inspired further exploration of the symmetrical idea. Modern elite players such as Fabiano Caruana and Anish Giri still deploy 2…b6 in the Queen’s Indian to steer the game into less-theoretical, strategic waters.
Illustrative Game
Caruana – Giri, Tata Steel Masters 2019
Giri’s early …b6 allowed speedy development and flexible responses to White’s central expansion. The game ended in a dynamic draw after tactical complications on the c- and e-files.
Typical Tactical Motifs
- Diagonal Tactics: …Bb7×g2 or …Bb7×e4 sacrifices can appear when White’s king remains in the center.
- c-File Pressure: Black often leverages …c5 (or …cxd4) to open the c-file, where the b7-bishop and rooks cooperate.
- Exchange on f3: In Queen’s Indian structures, …Bb4-a5×c3 reduces White’s central control and aids the …d5 break.
Interesting Anecdotes
- When Bobby Fischer needed only a draw against Petrosian in the 1971 Candidates Final, he surprised everyone with 2…b6 in a Queen’s Indian setup—demonstrating faith in its solidity under the highest pressure.
- Computer engines once criticized 2…b6 in the Sicilian as “too slow,” yet modern neural-net analysis has shown the line to be entirely sound and rich in hidden resources.
