King's Indian Defense · E64
Fianchetto Variation, Yugoslav System
1. d4 Nf6 2. c4 g6 3. Nf3 Bg7 4. g3 d6 5. Bg2 O-O 6. O-O c5
White's kingside bishop takes the long diagonal and Black's kingside bishop takes the long diagonal. White mirrors the g-bishop and denies Black the usual attacking targets: a positional KID where the centre and queenside count more than mating nets.
The first 4 moves, explained
- 1. d4 Stakes a claim in the centre, controlling e5, and frees the bishop and queen.
- 1... Nf6 Develops the knight to f6, eyeing d5 and e4.
- 2. c4 Fights for d5 from the flank - contesting the centre without committing a centre pawn.
- 2... g6 Prepares the fianchetto: the bishop will take the long diagonal via g7. Theory calls this the West Indian Defense.
