The Indian Defence: 1.d4 Nf6 2.c4... c5 arises after 1.d4 Nf6 2.c4 c5 and falls under ECO code A56. Here Black challenges White's central d-pawn from the side. White cannot simply capture with 3. dxc5?, since Black easily recovers the pawn with 3...e6 followed by ...Bxc5, having successfully traded off one of White's key central pawns in the process. The strongest way for White to maintain the pawn is 3. d5, which restricts Black's position and forces Black to find a way to undermine the resulting pawn chain. Passive defenses of d4 such as 3. e3?! or 3. Nf3?! are questionable because they allow Black to exchange the less important c-pawn for White's central d-pawn, diminishing White's grip on the center. With 10.2 million Lichess games across all rating levels, it is a well-established opening choice.
