Queen's Gambit Declined
ECO: D30–D69For blackclassicald4solid
Overview
By declining the gambit pawn with 2...e6, Black builds a strong central pawn structure at the cost of a slightly passive light-squared bishop.
Key Ideas
- Build the solid Orthodox structure with ...e6, ...d5, and ...Nf6.
- Watch for the minority attack on the queenside.
- Activate the light-squared bishop via b7 (or after ...c5).
- Aim for symmetric endgames where small advantages persist.
