Opening Name: King's Indian Defense: 5.Nf3 c5 6.d5 O-O
Moves: 1. d4 Nf6 2. c4 g6 3. Nc3 Bg7 4. e4 d6 5. Nf3 c5 6. d5 O-O
Description: This variation of the King's Indian Defense features Black challenging White’s center with ...c5 on move 5, aiming to undermine White’s central pawns. White responds with 6.d5, gaining space and closing the center. Black castles kingside with 6...O-O, preparing for a typical King's Indian counterattack on the flanks.
Characteristic: The move 5...c5 is a thematic break in the King's Indian, signaling Black’s intent to contest White’s pawn center immediately rather than waiting. White’s 6.d5 gains space but locks the center, leading to typical positional and pawn structure battles.
Attacking or Defensive: White’s setup with d5 is generally positional and space-gaining, focusing on controlling the center and cramping Black’s pieces, so it’s more on the defensive/positional side. Black, meanwhile, aims for a dynamic counterattack, often on the kingside or via breaks like ...b5 or ...e6, so Black’s approach is typically attacking.
Center Control: White occupies the center firmly with pawns on d5 and e4, exerting spatial dominance. Black contests the center indirectly, preparing pawn breaks to challenge White’s stronghold. Thus, the opening revolves around a strategic battle for central control.
