Queens Gambit Declined Modern Variation (1.d4 d5 2.c4 e6 3.Nc3 Nf6 4.Bg5) Chess Puzzles

The “queens gambit declined modern variation” is a QGD line where Black chooses a modern, flexible setup rather than the more classical, tightly committed structures. I don’t have a single universally agreed defining move-order for this exact Lichess-family label, so the most reliable way to identify it is by the resulting QGD position features: Black keeps pieces flexible and aims to challenge White’s central control without locking into an early, fixed pawn structure.
