The opening is characterized by an early d4 and c4 by White, and Nf6 and e6 by Black, followed by the development of both knights for each player. In this variation, Black chooses to capture the pawn on c4, which can lead to a more open and dynamic position. White's main goal is to regain the pawn on c4 and establish a strong pawn center, while Black aims to challenge White's center and create counterplay.

This variation is considered a solid choice for Black, as it avoids some of the more aggressive lines in the Queen's Gambit Declined. It is named after the city of Vienna, where it was first played in the 19th century. The opening has been played by many top-level players, including former World Champions Anatoly Karpov and Garry Kasparov.

In the middlegame, both sides have chances for active play, with White typically having a slight advantage due to the extra central pawn. Black can try to exploit the temporary pawn weakness on c4 and create counterplay on the queenside. Proper piece coordination and timely pawn breaks are essential for both sides to make progress in this opening.

Overall, this variation is a reliable and classical choice for players who prefer a balanced and strategic battle.
