Long-term bishop pressure down the g2 diagonal

Strategic ideas
- Combine a Queen's Gambit setup with a kingside fianchetto on g2
- Build lasting pressure along the g2–a8 diagonal with the Catalan bishop
- Recover the c4 pawn via Qa4+ or Qxc4 while the bishop remains active
- Dominate the d5 outpost once pieces are exchanged in the endgame
- Use the open c-file to generate lasting rook pressure after simplifications
Key themes
- Positional — The Catalan bishop on g2 exerts subtle but permanent pressure that is difficult to neutralise
- Space — The d4–c4 pawn formation gives White a space advantage that constrains Black's piece activity
- Open Files — The c-file opens naturally after pawn exchanges and becomes White's primary endgame weapon
Typical plans
White combines a Queen's Gambit setup with a kingside fianchetto, placing the bishop on g2 where it eyes the long diagonal and the c6–a8 squares. After Black captures on c4, White recovers the pawn while the g2 bishop exerts lasting positional pressure. The open c-file after simplifications typically gives White a long-term endgame advantage that is very difficult to neutralise.
