ECO D covers queen-pawn games and closed structures, including many Gambits and the Queen's Gambit complex. White develops a knight and keeps flexible transpositions into d4 or c4 setups. This entry tracks a longer branch in the opening tree. Use the diagram and SAN list to recognize the tabiya, then try the line against Maia to explore typical plans in practice.
