Key ideas for both sides
White
- Play Bg2 and short castling first, then c4 to pressure d5 like a Catalan.
- Against ...Bf5, play c4 and Qb3 to attack the b7 and d5 pawns.
- If Black takes on d4 after ...c5, recapture with the knight and use the g2 bishop.
- Against ...g6 lines, trade on d5 and play Nc3 for a symmetrical game.
Black
- 3...Bf5 develops the bishop before c4; follow with ...e6 and ...h6 for a safe retreat.
- 3...c5 hits d4; after Bg2 take on d4 and later push ...e5 for central space.
- 3...g6 and ...Bg7 lead to a solid, symmetrical double fianchetto structure with few weaknesses.
- Watch b7 after Qb3; keep the queen or a knight ready to protect it.
Plans and pawn structure
White's fianchetto on g2 aims at d5 and b7. White castles first and then plays c4, adding pressure on Black's center. Black can develop actively with ...Bf5 and ...e6, but must watch the b7 pawn after Qb3. With ...c5 Black opens the center, and after ...cxd4 and Nxd4 Black gains space with ...e5 to push the knight back. With ...g6 the game is calm and symmetrical.

How to play against it
As Black, develop the light-squared bishop early with ...Bf5 or ...Bg4, before c4 and Qb3 arrive. Then play ...e6 and ...c6 to keep d5 safe. Avoid leaving b7 loose once the White queen reaches b3, since d5 and b7 can both come under fire.
