A08 King’s Indian Attack: Sicilian Variation
Also filed here: Zukertort Opening.
A08 holds eight named lines from two openings, most of them (four) under King’s Indian Attack. It leaves A07, a position of the same name, with 3.Bg2. None of its eight lines contains a capture. That final move, by the bishop, opens a line for the rook on h1 and guards the rook on h1.
