ECO A covers irregular and flank openings—systems that skip the main e4/d4 fight early. 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.
