A06 Zukertort Opening
Also filed here: Nimzo-Larsen Attack.
A06 holds 13 named lines from two openings, most of them (ten) under Zukertort Opening. It leaves A04, a position of the same name, with 1...d5. Material is no longer level at the end of three of its lines; the widest gap, one pawn in Black’s favour, comes in Zukertort Opening: Pachman Gambit. That final move, by the d-pawn, covers c4 and e4 and opens a line for the bishop on c8 and the queen on d8.
