ECO A covers irregular and flank openings—systems that skip the main e4/d4 fight early. White gains queenside space immediately—the Sokolsky / Polish family. 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.
