The idea
White avoids d4 entirely, fianchettoes and plays a slow kingside build-up with f4 — a positional antidote to the open Sicilian.
Main line: 1.e4 c5 2.Nc3 Nc6 3.g3 g6 4.Bg2 Bg7 5.d3 d6 6.Be3 e5 7.Qd2 Nge7
What White wants
- Build with g3, Bg2, d3, Be3 and Qd2, then push f4
- Attack on the kingside with f4 and the rook lift
- Keep the position closed and avoid Black's tactical preparation
What Black wants
- Play ...e5 or ...b5 to gain space and counterattack
- Develop with ...Nge7 and ...Be6 and hit the d3 pawn
- Break open the centre before White's f4 push arrives
Key idea
Understand this and the moves stop needing to be memorised.
Central breaks give the bishop more scope
The g2 bishop's diagonal runs through f3 and e4, where White's own e-pawn initially limits it. The d3 pawn is not on that diagonal. White often prepares f4 to challenge Black's centre, while keeping the option of e5 or other central exchanges.
Common mistake
Starting the kingside attack without completing development. f4 against ...e5 is a standard Closed Sicilian structure, not a refuted plan; White should coordinate Nf3, castling and the central tension before assuming the pawn advance generates threats by itself.
Mistake example: Nge7.
