Queens Gambit Declined Tartakower Defense Interference in Chess

Queens Gambit Declined Tartakower Defense Interference is an interference motif in the QGD Tartakower structure, typically arising after moves like 1.d4 d5 2.c4 e6 3.Nc3 Nf6 4.Bg5 Be7 5.e3 O-O 6.Bd3 dxc4 (or related move orders). The defining feature is that a key defender (often on the e-file or c-file) is needed to control a critical square, but a tactical shot forces that defender to “get out of the way,” breaking the defense.
