E92. 1.d4 Nf6 2.c4 g6 3.Nc3 Bg7 4.e4 d6 5.Nf3 O-O 6.Be2 e5 7.Be3 #The Gligoric System of the King's Indian is characterised by this non-committal move. White gets all his minor pieces off the back rank without compromising the central tension. This flexible system was a Kasparovian favourite in his youth and later, Karpov even used it several times against him in their World Championship matches.
