The Queen's Gambit Declined arises after 1.d4 d5 2.c4 e6 and falls under ECO code D30. By playing 2...e6, Black turns down the gambit in the classical manner, reinforcing the d5 pawn while simultaneously opening a diagonal for the dark-squared bishop to develop. The downside is that the e6 pawn obstructs the c8-h3 diagonal, hemming in the light-squared bishop. How to activate this problematic piece remains one of the central strategic questions for Black throughout the QGD. With 68.3 million Lichess games across all rating levels, it is one of the most popular openings.
