1.d4 — the closed and Indian games
Grünfeld, Fianchetto Variation
1.d4 Nf6 2.c4 g6 3.Nf3 Bg7 4.g3 d5 5.Bg2 O-OECO D70–D79
White meets the Grünfeld with a fianchetto of their own, avoiding the sharpest Exchange lines. Both bishops rake the long diagonals, and the game becomes a subtle strategic contest over the centre and the c-file rather than a forced theoretical duel — a positional way to fight the Grünfeld.
Key ideas
- The g3/Bg2 setup contests the long diagonal and supports a later cxd5 or e4 at the right moment.
- Black plays …dxc4, …c5 or …c6 systems, striking at the centre in true Grünfeld style.
- It's a manoeuvring battle where understanding the central tension beats memorising forcing lines.
