Modern Defense
Initial Moves: 1.e4 g6 2.d4 Bg7 3.Nc3 d6
Strategic Summary & Main Idea
The Modern Defense lets White occupy the centre so Black can attack it later with fianchettoed pieces and breaks such as ...c5 or ...e5. By delaying the g8 knight, Black keeps maximum flexibility and can transpose into Pirc or King's Indian structures.
Typical Plans for White
- Using the space advantage with f4, Nf3 and e5 at the right moment
- Setting up the 150 Attack with Be3, Qd2 and queenside castling
- Restraining the g7 bishop before starting operations on the wings
Typical Plans for Black
- Attacking White's centre with ...c5, ...e5 or ...b5
- Fianchettoing the bishop on g7 to press the long diagonal
- Choosing where the g8 knight belongs according to White's set-up
