The big idea

What the Grünfeld Defence is really about.

A bold, hypermodern answer to 1.d4. Instead of occupying the centre, Black invites White to build a broad pawn front — and then sets out to tear it down. The fianchettoed bishop on g7 rakes the long diagonal while ...c5 and piece pressure pour onto the centre. It is dynamic, double-edged chess where Black trades space for activity.

White's plan: Accept the invitation: grab the centre with pawns on d4 and e4, develop behind them, and try to prove the space advantage by keeping the pawns rolling and the centre intact.
Black's plan: Let White overextend, then strike with ...c5 and the g7-bishop down the long diagonal, hitting d4 and the queenside until White's proud centre becomes a target rather than a strength.

After 1.d4 Nf6 2.c4 g6 3.Nc3 d5

The Grünfeld lets White build a big pawn centre, then blasts at it: ...dxc4, the ...Bg7 fianchetto, and ...c5 hitting d4. Black's pieces target the centre from a distance.

White builds a big d4/e4 pawn centre in the Grünfeld. How should Black treat it?
