The King's Indian Attack (or KIA), also known as the Barcza System (after Gedeon Barcza) is a chess opening 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. Characteristics The KIA is a mirror image of the setup adopted by Black in the King's Indian Defence. But, because of White's extra tempo, the nature of the subsequent play is often different from that of a typical King's Indian Defence. By its nature, the KIA is a closed, strategic opening that presents its practitioner with common themes and tactics and a comfortable middlegame against various defences. White's most common plan involves a central pawn push, e4–e5, leading to a central bind, , and concrete attacking chances on a kingside-castled black king. Black's resources—more space for example—are not to be underestimated. In fact, this asymmetry often leads to violent middlegames and neatly constructed mating nets involving sacrifices. Use The KIA is often used against the semi-open defences where Black responds asymmetrically to e4, such as in the French Defence, Sicilian Defence, or Caro–Kann Defence. Yet it can also be played against Black's more common defenses, usually through a move order that begins with 1.Nf3 and a later fianchetto of the white-square bishop. For this reason, transpositions to the Réti Opening, Catalan Opening, English opening or even the Nimzo-Larsen Attack (after b3 and Bb2) are not uncommon. The KIA is considered a solid opening choice for White, although less ambitious than many more popular openings. Though rarely used at
