The Queen's Gambit Declined: 1.d4 d5 2.c4... Nbd7 arises after 1.d4 d5 2.c4 e6 3.Nc3 Nf6 4.Bg5 Nbd7 and falls under ECO code D51. The move 4...Nbd7 often signals Black's intention to enter the Cambridge Springs Defense after 5.Nf3 c6 6.e3 Qa5 — a reliable system in the QGD that appeals to both amateurs (for its straightforward themes) and grandmasters alike. This position also contains a well-known tactical trap. If White plays 5.cxd5 exd5, reaching a QGD Exchange-type structure that is perfectly fine for both sides, the blunder 6.Nxd5?? looks like it wins a pawn since the f6 knight appears pinned. However, Black can capture with 6...Nxd5!, and after 7.Bxd8, the stunning 7...Bb4+! forces 8.Qd2 as the only legal move, whereupon Black regains the queen and ends up a full minor piece ahead.

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.
