Idea principal de las blancas
White aims to fianchetto the king's bishop to g2, pressuring Black's d5 pawn and the b7 square. The early g4 push seeks to control f5 and prepare a kingside space advantage, often leading to sharp play if Black allows.

Black solidifies the center with c6, supporting d5 and preparing ...e5 or ...Bf5. Black aims to prove that White's g4 pawn is a weakness, targeting it with moves like ...h5 or ...Qd6, while maintaining a classical pawn center.
Planes estratégicos de las blancas
- Plan 1: Kingside Storm Push h4-h5 to open lines against Black's king, often after castling kingside, using the g-pawn as a battering ram.
- Plan 2: Central Pressure Play d3 and e4 to challenge Black's d5 pawn, aiming to trade on d5 and activate the bishop on g2.
- Plan 3: Quick Development Develop Nc3 and Nf3, then castle queenside (O-O-O) to avoid the g4 weakness and launch an attack.
