Ideas
ECO A covers irregular and flank openings—systems that skip the main e4/d4 fight early. White prepares a delayed central push or a kingside fianchetto from an unusual move order. The variation is defined by a short, recognizable move order. Use the diagram and SAN list to recognize the tabiya, then try the line against Maia to explore typical plans in practice.
