The King's Indian Defense arises after 1.d4 Nf6 2.c4 g6 and falls under ECO code A50. By playing 2...g6, Black signals a hypermodern development plan: the dark-squared bishop will be fianchettoed to g7, from where it exerts long-range pressure on White's centre alongside carefully timed pawn breaks. Several important themes are already in play at this early stage. Keeping the dark-squared bishop is essential for Black's kingside safety after castling, since 2...g6 weakens the dark squares around the king, and without the bishop covering f6 and h6, those weaknesses can prove fatal. At the same time, the g7 bishop carries significant offensive potential: if White opens the centre through pawn exchanges, the bishop can become a powerful attacking piece along the long diagonal toward White's queenside. This pawn structure almost always leads to one of two major systems. In the King's Indian Defence proper, Black castles quickly on the kingside, conceding White a substantial pawn centre but planning to chip away at it with pawn advances and reclaim territory. In the Grunfeld Defence, Black waits for White to play Nc3 before striking with ...d5, seeking counterplay along the long dark diagonal with the aid of ...c5, while White leans on the advantage of a broad central pawn mass. With 31.5 million Lichess games across all rating levels, it is one of the most popular openings.

Common Mistakes to Avoid
- Allowing White to build an overwhelming center: Hypermodern openings allow White space in the center, but you need to strike back at the right moment. Delaying the counterattack too long can leave you without active play.
