The central idea
The Queen's Gambit Declined meets 1.d4 d5 2.c4 with ...e6 and a resilient central structure. Black gives White space for a while, then targets the center with ...c5 or piece pressure.
Typical plans
- Develop the kingside and decide how to free the c8 bishop.
- Use ...c5 or ...e5 breaks when prepared.
- Keep the d5 pawn supported while improving the queenside pieces.
Common mistakes
- Locking in the c8 bishop without a release plan.
- Exchanging in the center without understanding the resulting minority or hanging-pawn structure.
- Defending passively and allowing White a risk-free space advantage.
