About the Queen's Gambit Declined
After 1.d4 d5 2.c4, Black keeps the d5 pawn with ...e6 instead of taking on c4. It is solid, classical and very reliable.
Black develops calmly: ...Nf6, ...Be7, ...O-O, and keeps a strong pawn on d5.
The light-squared bishop on c8 is often stuck behind e6; freeing it is a main task.
Black frees the position with the breaks ...c5 or ...e5; White often plays for a minority attack with b4-b5.
