Queens Gambit Declined Tarrasch Defense Deflection in Chess

In the Queens Gambit Declined Tarrasch Defense, the deflection motif aims to pull a key defender away from a critical square or line. A defining feature is the Tarrasch structure with ...c5 and the central tension around d4/e4, where pieces often guard the d4 pawn, the c5 break, or the c-file. The “deflection” happens when one side forces that defender to respond to a threat, allowing a follow-up win of tempo, pawn, or tactical advantage.
