Synonym(s)KIA

The King's Indian Attack (or KIA) is a chess opening system where White adopts the setup more commonly seen being played by Black in the King's Indian Defence. The King's Indian Attack is characterised by the following moves: the central pawns are developed to e4 and d3, the knights are developed to d2 and f3, the king's bishop is fianchettoed at g2 following the g-pawn's move to g3, and White castles kingside.

This pattern can either be achieved via a 1.e4 move order (typically against either the French Defence or a Sicilian Defence with a subsequent ...e6) or as a universal system starting with 1.Nf3.

History

The use of the King's Indian Attack at grandmaster level was originally an offshoot from the widespread use of the King's Indian Defence in the 1950s. As grandmasters began to appreciate the advantages of playing the King's Indian Defence as Black, the use of the same system as White, with an extra move in hand, inevitably became attractive.

Prominent players who have employed the King's Indian Attack include Bobby Fischer (mostly in his early career), Mikhail Botvinnik, Vasily Smyslov, Tigran Petrosian, Leonid Stein, Rafael Vaganian, Ljubomir Ljubojevic, Gregory Kaidanov, Igor Glek, Alexander Morozevich, Victor Bologan, and Levon Aronian. The use of the KIA was also advocated by the prominent chess trainer IM Mark Dvoretsky, [1] who also employed the system in his own games.

Today the King's Indian Attack is relatively uncommon at grandmaster level. The most frequent high-level practitioner is Egyptian grandmaster Bassem Amin. The KIA is popular at the club level, however, because of its system-like elements, repeatable middlegame plans, and the ability to launch a kingside attack from a stable position.

A typical position in the King's Indian Attack

In the King's Indian Attack, White uses the same setup adopted by Black in the King's Indian Defence. Due to White's extra tempo, however, the nature of the subsequent play is often different from that of a typical King's Indian Defence. The King's Indian Attack is most frequently employed against Black setups including an early ...e6, and in these situations Black is effectively a move down in a theoretically unimportant line of the King's Indian Defence. For example, after 1.e4 e6 2.d3 d5 3.Nd2 c5 4.Ngf3 Nf6 5.g3 Nc6 6.Bg2 Be7 7.0-0 0-0 8.Re1 (see diagram) Black is playing the White side of a very tame line of the King's Indian Defence where the queen's bishop on c8 is trapped behind the pawn chain . If Black were to attempt to resolve this situation by playing a subsequent e6-e5 they would then find themselves two moves down in a standard mainline position from the King's Indian Defence. This illustrates the central dilemma faced by Black in standard Kings Indian Attack lines.

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 the central pawn push e4–e5, leading to a central bind, kingside space , and practical attacking chances against the kingside-castled black king. White's strategy differs from standard French Defence lines because the e5-pawn will be defended by pieces (Nf3, Re1, Bf4, and possibly Qe2) rather than by pawns, thus avoiding the pawn weakness on d4 which is Black's usual target in the French.

Typical lines

The King's Indian Attack most frequently arises against the French Defence using the move order 1.e4 e6 2.d3 d5 3.Nd2 (to avoid an exchange of queens after 3...dxe4) 3...c5. Identical lines can arise via a Sicilian Defence move order, typically via 1.e4 c5 2.Nf3 e6 3.d3 and a subsequent Nbd2. If Black plays a Sicilian variation with 2...d6 or 2...Nc6, White can still continue with the King's Indian Attack setup, but in these cases it would be considered less effective (Black will either have a pawn on d6, meaning that the characteristic pawn push e4–e5 will not create a bind, or a pawn on e5, preventing e4-e5 altogether).

After 1.e4 e6 2.d3 d5 3.Nd2 c5, the game might typically proceed as follows: 4.Ngf3 Nf6 5.g3 Nc6 6.Bg2 Be7 7.0-0 0-0 8.Re1 (see diagram in previous section). White will now look to play e4–e5, cramping Black, and then proceed with moves such as Nf1, Bf4, Qe2, h4, N1h2 (or Ne3), h5, g4 (or Ng4) with a kingside attack. Note that the position after 8.Re1 could also have been obtained via a 1.Nf3 move order (e.g. 1.Nf3 d5 2.g3 Nf6 3.Bg2 c5 4.0-0 Nc6 5.d3 e6 etc.).

King's Indian Attack vs Caro-Kann

The Kings Indian Attack setup is also sometimes employed against the Caro–Kann Defence, e.g. 1.e4 c6 2.d3 d5 3.Nbd2 e5 4.Ngf3 Bd6 5.g3 etc. Some practitioners at club level, determined to use the KIA as a system, may even use the setup after 1.e4 e5 (giving a reversed Pirc Defence), although this cannot be regarded as a genuine attempt to secure an advantage from the opening.

When employed via a 1.Nf3 move order, play sometimes develops along the lines of the Franco-Sicilian type structures considered above. Alternatively, Black can look to develop the c8-bishop outside of the pawn chain, either to Bg4 (the Keres System, e.g. 1.Nf3 d5 2.g3 Nf6 3.Bg2 c6 4.0-0 Bg4) or to Bf5 (giving a reversed London System).

Black can also develop along the lines typically adopted by White in the King's Indian Defence: e.g. 1.Nf3 d5 2.g3 c5 3.Bg2 Nc6 4.0-0 e5 5.d3 Nf6. This line is referred to as the Reversed King's Indian.

The London System is an opening system in chess where White opens with 1.d4 and develops the dark-squared bishop to f4, then supports the d4-pawn with pawns on e3 and c3. The other bishop is developed to d3 and the knights typically to f3 and d2. This set-up often results in a closed game. The London System can be used against virtually any Black defence and thus comprises a smaller body of opening theory than many other openings. Although it has a reputation as a solid opening, the London System has faced criticism for its tedious nature and lack of dynamic play.
