Queens Gambit Declined Manhattan Variation (1.d4 d5 2.c4 e6 3.Nc3 Nf6 4.Bg5 Nbd7 5.e3 Bb4) Chess Puzzles

The queens gambit declined manhattan variation is a QGD sideline where the game reaches a Manhattan-style structure after Black declines the gambit and White commits to a specific central/queenside setup. However, I don’t know the exact, widely accepted defining move order that uniquely distinguishes “Manhattan” from other QGD sub-variations, so I can’t safely provide a precise move sequence without risking inaccuracy. For intermediate players, the practical meaning is that you should expect a QGD pawn structure with White aiming for pressure on the queenside/center while Black seeks solid pie
