The A07 King's Indian Attack Challenge

The King's Indian Attack (KIA) is a chess opening system for White, most notably used by Bobby Fischer. White's most common plan involves a central pawn push, e4–e5, leading to a central bind, kingside space, and concrete attacking chances on a kingside-castled black king. Black's resources—more queenside space for example—are not to be underestimated. In fact, this asymmetry often leads to violent middlegames and neatly constructed mating nets involving sacrifices.
