ECO A covers irregular and flank openings—systems that skip the main e4/d4 fight early. White makes a useful waiting move on the queenside before committing the center. 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.
