White to move. Main line: 1. c4 e5 2. Nc3 Nc6 3. g3 g6 4. Bg2 Bg7 5. e4 d6 6. Nge2 f5 7. d3 Nf6
The pawns on c4, e4 and d3 control key dark squares and restrict Black’s central breaks. White develops the g1-knight to e2 because f3 is less useful in this structure and the knight may later travel to g3 or c1–e2–c3 routes.
Black mirrors the kingside fianchetto and challenges the bind with ...f5. That break creates activity but also opens lines near Black’s king, so both sides must decide whether to close the center, exchange on f5 or prepare play on the opposite wing.
A setup is not a sequence to repeat blindly. White’s space can support a kingside attack or queenside expansion, but the pieces must match the chosen plan. Black’s freeing breaks ...f5 and ...b5 determine where the position will open.
