The Queen's Gambit Declined: 1.d4 d5 2.c4... Nf6 arises after 1.d4 d5 2.c4 e6 3.Nc3 Nf6 and falls under ECO code D35. This is the classical main line of the Queen's Gambit Declined, where Black develops a minor piece, contests the center, and moves a step closer to kingside castling. White has several continuations, some of which may transpose into one another. The exchange variation 4.cxd5 produces the well-known Carlsbad pawn structure, which — unlike the typically quiet exchange lines in the French or Slav — offers White several aggressive plans, including the queenside "minority attack" or preparation for a central breakthrough with e2-e4 or e3-e4. Alternatively, 4.Nf3 is the solid classical continuation, giving Black a wide range of developmental choices and potentially leading into some of the sharpest variations of the Queen's Gambit Declined. With 36.7 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.
