Ideas
ECO D covers queen-pawn games and closed structures, including many Gambits and the Queen's Gambit complex. White builds a pawn center and keeps the position more closed than after 1. e4. This entry names the opening after the first moves. Use the diagram and SAN list to recognize the tabiya, then try the line against Maia to explore typical plans in practice.
