D00 Queen’s Pawn Game
Also filed here: Blackmar-Diemer Gambit, Amazon Attack.
D00 holds 72 named lines from three openings, most of them (49) under Blackmar-Diemer Gambit. It leaves A40, a position of the same name, with 1...d5. Material is no longer level at the end of 47 of its lines; the widest gap, two pawns in Black’s favour, comes in Blackmar-Diemer Gambit Accepted. With 72 named lines it is the third-largest code of all 500 codes. Its deepest line, Blackmar-Diemer Gambit Accepted: Euwe Defense, Zilbermints Gambit, runs to 9.Kh1, the longest of the 7 Queen’s Pawn Game codes.
