The King's Indian Defence: 1.d4 Nf6 2.c4... 7.Bc4 arises after 1.d4 Nf6 2.c4 g6 3.Nc3 d5 4.cxd5 Nxd5 5.e4 Nxc3 6.bxc3 Bg7 7.Bc4 and falls under ECO code D86. Placing the bishop on c4 gives it an active diagonal, but this choice comes with a cost: developing the knight to f3 becomes problematic because Black can play Bg4!, generating severe pressure against d4. White must therefore choose between different piece configurations — Be2 paired with Nf3, Bc4 paired with Ne2, or Bc4 with Nf3 and h3 to prevent Bg4. The Bc4 setup prioritizes bishop activity, whereas the Be2 alternative favors the knight's placement. The Be2/Nf3 arrangement has grown increasingly popular since the 1980s. With 644,360 Lichess games across all rating levels, it is a specialized opening choice.
