In this variation of the Queen's Gambit, Black opts to capture the pawn on c4 and develop pieces actively, particularly targeting the e4 square. Key ideas include creating counterplay with ...e6, followed by potential pawn breaks with ...c5 or ...f5, while White typically aims for central control and piece development, often considering c3 to reclaim the pawn on c4. This setup appeals to players who enjoy dynamic play and are comfortable with complex pawn structures, as it often leads to rich middlegame positions with chances for both sides.
