The Indian Defence: 1.d4 Nf6 2.c4... 3.Nf3 arises after 1.d4 Nf6 2.c4 e6 3.Nf3 and falls under ECO code E10. The knight develops to an active square, reinforcing d4 and e5 while bringing White closer to kingside castling. One drawback is that it blocks the f-pawn, which can serve as a useful lever in certain lines. A major reason White chooses 3.Nf3 over 3.Nc3 is to sidestep the Nimzo-Indian Defence (3.Nc3 Bb4). While 3...Bb4+ remains possible after 3.Nf3, it leads to the Bogo-Indian Defence, which is generally considered less promising for Black than the Nimzo-Indian. On the other hand, because 3.Nf3 does not directly support the e4 break or contest the d5 square, it is slightly more restrained than 3.Nc3. Still, it is a solid choice that offers White numerous paths to a quiet, positional edge. Beyond the Bogo-Indian, Black can steer play toward the Queen's Indian, the Benoni, or various other transpositions. With 11.1 million Lichess games across all rating levels, it is one of the most popular openings.
