 | | Black may choose to mirror White's move and reply with "e5" for the same reasons, leading to openings such as the Ruy Lopez, Giuoco Piano (including the Evans Gambit variant), and King's Gambit. |
 | | This leads to openings such as the Queen's Gambit, King's Indian Defense, Nimzo-Indian, Bogo-Indian, and Queen's Indian Defense, and Dutch Defense. |
 | | Black can accept the gambit with dxc4, playing "Queen's Gambit Accepted", which is a risky way to play this gambit. |
