Queens Gambit Declined Deflection in Chess

In the Queens Gambit Declined deflection motif, one side plays a move that forces a crucial defender to leave its post—typically by attacking it, offering a capture, or creating a tactical threat. In QGD structures, this often targets the piece that guards a central square (like d5/e4) or protects the queen/king-side coordination after moves such as ...Nf6 and ...Be7. The defining idea is: deflect the defender, then win something immediately—often a pawn, a tempo, or a favorable exchange—because the position’s key tactic opens up.
