Kasparov – Karpov1984
Game three of the 1984 match, and Karpov's first win in it: the Queen's Indian between the two players this repertoire names for it. The Fianchetto line with 4…Ba6, reached by a slightly different order and then the repertoire's own position to the move, and a game decided by the queenside — the a-pawn falls on move twenty-six, and a rook ending forty moves long collects on it.
