Queens Gambit Declined Westphalian Variation (1.d4 Nf6 2.c4 e6 3.Nf3 d5 4.Nc3 Bb4 5.Bg5 Nbd7 6.e3 c5) Chess Puzzles

I can’t reliably name the exact, defining move-order for the “queens gambit declined Westphalian variation” from my current knowledge. The label is used inconsistently across sources, so I don’t want to invent a move sequence. In general, when players refer to this variation, they mean a specific QGD sideline reached from the main QGD structure where Black chooses a particular setup and White responds with a corresponding plan—so the “Westphalian” part is about the distinctive move-order/placement that separates it from nearby QGD branches.
