A structure where White builds a big pawn center on c3, d4 and e4 while Black attacks it with pieces and the pawn break ...c5, relying on the bishop on g7 and quick counterplay. Black allows White to occupy the center with pawns, then undermines it. After ...d5 and the exchanges on d5 and c3, White gets a broad center and a half-open b-file, while Black gets [active pieces](https://georgelichess.com/glossary/piece-activity.md) and the long [diagonal](https://georgelichess.com/glossary/diagonal.md) for the [bishop](https://georgelichess.com/glossary/bishop.md) on g7. Black's tools are the c5 break, a queen on a5, a rook on c8, and pressure on d4. The bishop on g7 eyes the pawn on d4 and the rook on a1, so any weakness around d4 is serious. Black often plays ...Nc6 and ...Bg4 to add pressure. White's plan is to keep the center safe, develop the pieces smoothly, and use the space to attack. Typical moves are Be3, Rb1, Qd2 and a kingside attack with h4-h5. If Black's pressure fails, White's center turns into a strong attacking force. Common errors are for White to allow ...c5 and ...Qa5 without a response and for Black to trade the bishop on g7 too early. Practical tip: against the Grunfeld's big center, count how many attackers Black has on d4 versus how many defenders White has before deciding between a quiet plan and a sharp plan. ## Example position White has pawns on c3, d4 and e4, and Black's bishop on g7 and queen on a5 press on d4. Position (FEN): `rnb1k2r/pp2ppbp/6p1/q1p5/3PP3/2P1BN2/P4PPP/R2QKB1R w KQkq -` A neighboring idea is [London system setup](https://georgelichess.com/glossary/london-system-setup.md). The London system setup is a White plan that brings the dark-squared bishop to f4 before e3 can shut it in, then builds a sturdy triangle of pawns on c3, d4 and e3 that suits nearly any Black reply. Compare it with [Symmetrical position](https://georgelichess.com/glossary/symmetrical-position.md). A symmetrical position is one where both sides have the same pawn structure and similar piece placement, so the fight depends on tempo, activity and who first creates a concrete imbalance.
