Barcza System – King’s Indian Attack (A07)

King's Indian Attack (or KIA), also known as the Barcza System (after Gedeon Barcza), is a chess opening system for White.

The opening is not a series of specific moves, but rather a system that can be played from many different move orders. Though the KIA is often reached via 1.e4 followed by d3, Nd2, Ngf3, g3, Bg2, and 0-0, it can also arise from 1.g3, 1.Nf3, or even 1.d3.

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 closed 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 the highest levels except to avoid certain pet lines, it is extremely popular at the club level, because it is easier to learn than other openings that require memorising specific move orders to avoid bad positions.

Gedeon (Gideon) Barcza (August 21, 1911 in Kisújszállás – February 27, 1986 in Budapest) was a Hungarian chess master.

In 1940, Barcza took third place, behind Max Euwe and Milan Vidmar, at Maróczy Jubiläum in Budapest. In September 1942, he took sixth place at the first European Championship in Munich: the event was won by Alexander Alekhine. In 1948, he took second place in Karlovy Vary: the event was won by Jan Foltys. In 1948, he tied for second/third place in Venice: the event was won by Miguel Najdorf. In 1950, he tied for second/fourth place in Salzbrunn (Szczawno Zdrój): the event was won by Paul Keres. In 1952, he took fifteenth place in Saltsjöbaden (interzonal). In 1957, he won in San Benedetto del Tronto. In 1961, he took third place in Vienna. In 1962, he tied for third/sixth place in Moscow. In 1962, he tied for fourteenth/fifteenth place in Stockholm (interzonal).

Barcza won the Hungarian Chess Championship eight times (1942, 1943, 1947, 1950, 1951, 1955, 1957, and 1958) and played for Hungarian team in seven Chess Olympiads (1952, 1954, 1956,1958, 1960, 1962, and 1968). He was awarded the Grandmaster title in 1954.
