The Open Games (1...e5) arises after 1.e4 e5 and falls under ECO code C20. Known as the Open Game or Double King's Pawn, 1...e5 represents Black's most traditional answer to 1. e4, immediately claiming an equal stake in the centre and opening lines for piece development. Crucially, it is one of the rare replies that directly challenges White's ambition to play d4. The symmetry, however, cuts both ways: as long as the position remains a mirror image, White's first-move advantage persists, which partly explains a gentle decline in the opening's popularity over the course of the 20th century. Because the e5 pawn sits undefended, White can steer development in a way that pressures it, limiting Black's options, and this is in fact White's most frequent strategy, though quieter setups that avoid an immediate attack are also viable. When White does target e5, the initiative stays firmly in White's hands, compelling Black to respond to threats rather than pursue independent plans. With 1314.2 million Lichess games across all rating levels, it is one of the most popular openings.
