Queens Gambit Declined Orthodox Defense Deflection in Chess

In the Queens Gambit Declined Orthodox Defense, “deflection” is a tactical idea where White forces Black’s key defender away from a critical square or line. A defining feature is the typical QGD setup with ...Nf6, ...e6, and the queenside pawn tension around c5/d5, where one piece often guards the central break or the c5 pawn. The deflection move sacrifices tempo or a pawn temporarily to remove that defender, enabling a winning follow-up like winning the c5 pawn, undermining d5, or improving White’s piece placement.
