Hans Niemann's Brilliant Opening Choice!
55The King's Indian Attack (or KIA), also known as the Barcza System (after Gedeon Barcza) is a chess opening system for White, characterized by several moves. The center pawns are developed to e4 and d3, the knights are developed to d2 and f3, the king's bishop fianchettoes at g2 following the g-pawn's movement to g3, and White castles kingside. The resulting arrangement has multiple positional themes: the pawn at d3 and the knight at d2 both defend the pawn at e4, the knight at f3 attacks the center, the fianchettoed bishop may influence the center following subsequent moves, and castling removes the king to safety while bringing a rook into the game.
Unlike other chess openings, The King's Indian Attack is not a specific sequence of moves, but rather a system for White where the moves may be permuted at the player's discretion, in response to the moves of the black pieces. When a game opens with most or all of the above moves, to the exclusion of moves which typify other openings, the game may be described as a King's Indian Attack.
