The King's Indian Defence: 1.d4 Nf6 2.c4... 3.Nc3 arises after 1.d4 Nf6 2.c4 g6 3.Nc3 and falls under ECO code E61. By developing the knight to c3, White prepares the e4 advance while retaining flexibility to enter multiple systems against the King's Indian. One of Black's most potent options here is the Grunfeld Defence with 3...d5, where the main line 4.cxd5 Nxd5 5.e4 Nxc3 6.bxc3 Bg7 creates a classic hypermodern structure — White holds an imposing pawn center that Black attacks from a distance using the dark-squared bishop and a ...c5 pawn break. The alternatives 3...Bg7 and 3...d6 follow the traditional King's Indian approach, remaining among the most respected and widely played setups at all levels.
