The Queen's Gambit Declined: 1.d4 d5 2.c4... 3.Nc3 arises after 1.d4 d5 2.c4 e6 3.Nc3 and falls under ECO code D31. By developing the knight to c3, White increases pressure on d5 and gains control of the e4 square, preparing a future e4 pawn break. Black has several important responses. After 3...Nf6, Black defends d5 and contests e4, though this also removes the queen's guard over g5, giving White the option of 4.Bg5 to pin the knight. If Black plays 3...c6, the d-pawn gains extra support and Black controls b5, potentially allowing ...dxc4 followed by ...b5 in the future. White can respond to 3...c6 with 4.Nf3, which can lead to the sharp Noteboom variation, or try 4.e4!?, entering the Marshall Gambit in the Semi-Slav, where White sacrifices a pawn for the bishop pair and attacking chances against Black's king — exploiting the fact that 3...c6 does little for development and does not control e4. Another key option for Black is 3...c5, the Tarrasch Defence, which immediately challenges the d4 pawn in a bold fight for central space. Black typically accepts an isolated queen's pawn in return for an active light-squared bishop and dynamic piece play. With 40 million Lichess games across all rating levels, it is a well-established opening choice.

Common Mistakes to Avoid
- Overextending without backup: When playing a gambit, each attacking move should have a purpose. Random checks and threats without coordination can leave your own position exposed once the initiative fades.
- Releasing central tension too early: The tension between the d5 and c4 pawns is a central feature of this opening. Capturing or pushing too early can give your opponent a free hand in the center.
