Queen's Gambit Declined Capture Defender Chess Puzzles

Queen's Gambit Declined Capture Defender is a motif in the Queen's Gambit Declined where Black reinforces the pawn on d5 after meeting 1.d4 d5 2.c4 with ...e6 and often ...Nf6, preparing to hold or recapture on c4 if needed. The defining feature is that Black's pieces and pawns are arranged to defend the d5 center and make the queen's gambit capture on c4 less effective for White.
