Key ideas behind this line

  • Fianchetto the bishop to g2 and pressure the long diagonal, targeting Black's d5 and the queenside light squares.
  • Combine the c4-pawn with Nc3 to clamp down on d5; meet ...d5 with cxd5 to open the bishop and play against the resulting structure.
  • In the Symmetrical, break with d4 (or expand with b4) to create central tension while Black mirrors and aims for ...d5 or a Hedgehog with ...e6/...b6.

Anti-Benoni: 3...d5 4.cxd5

Anglo-Indian: 1...Nf6 2.Nc3 g6 3.e4 (Botvinnik vs KID)

Black builds a Slav-like wall and grabs the c4-pawn; White fianchettoes, castles and regains the pawn with Qc2/Na3, emerging with smooth development and the long-diagonal bishop.

A double-fianchetto Hedgehog reached via Reti move-orders; White grabs the center with d4 and the centralized queen, restraining Black's freeing breaks and keeping a pleasant space bind.

Reversed Sicilian: 4.e3 / Bg2 Setup vs ...d6

Black sets up a solid King's-Indian-style wall with ...d6 and ...g6; White completes the double fianchetto-style structure and prepares the standard b4 queenside expansion where he holds the initiative.
