The plans for both sides are roughly the same as in the main variation. 7.d5 is the Petrosian Variation, so named for the 1963–69 world champion Tigran Petrosian, who often essayed the line in the 1960s, with Vladimir Kramnik playing this variation extensively in the 1990s.8.Bg5 h6 9.Bh4 Qe8 10.Bxf6 Bxf6 11.c5!, which is not totally reliable for Black.8.d5 Nc5 9.Qc2 a5 may transpose into the Petrosian Variation (see below).8.dxe5 dxe5 9.Qxd8 Rxd8 with even chances.Play commonly continues 8.Be3 Ng4 9.Bg5 Qe8 ! but White has also tried:
The purpose of this awkward-looking move is to transfer the knight to c5 after White's eventual d5, while guarding c7 if Black should play. 7.0-0 Na6 has seen some popularity recently.White still has an advantage in most lines. Made popular in the mid-1990s by the Russian Grandmaster Igor Glek, new ideas were found for White yet some of the best lines for White were later refuted. 7.0-0 exd4 8.Nxd4 is also possible, although White's extra space usually is of greater value than Black's counterplay against White's centre.7.0-0 Nbd7 is the Old Main Line, and is playable, though less common nowadays than 7.Nc6.9.b4, the Bayonet Attack, introduced by Korchnoi in the 1970s, used to put top players off playing this line, but it has recently been revived by Radjabov. Typically, White will try to attack on the queenside by preparing the pawn break c4–c5, while Black will attack on the kingside by transferring their knight from f6 to d7 (usually better placed than at e8, as it helps slow White's queenside play with c4–c5), and starting a kingside pawn storm with f7–f5–f4 and g6–g5.

In the early 2000s the opening's popularity suffered after Vladimir Kramnik scored excellent results against it, so much so that even Kasparov gave up the opening after relentless losses to Kramnik. It is a dynamic opening, exceptionally complex, and a favourite of former world champions Garry Kasparov, Bobby Fischer, and Mikhail Tal, with prominent grandmasters Viktor Korchnoi, Miguel Najdorf, Efim Geller, John Nunn, Svetozar Gligorić, Wolfgang Uhlmann, and Ilya Smirin having also contributed much to the theory and practice of this opening. Until the mid-1930s, the King's Indian Defence was generally regarded as highly suspect, but the analysis and play of three strong Soviet players in particular- Alexander Konstantinopolsky, Isaac Boleslavsky, and David Bronstein-helped to make the defence much more respected and popular. arose in the mid-twentieth century and are attributed to Hans Kmoch.
