Blackmar Diemer Gambit Other Variations Deflection in Chess

In the Blackmar-Diemer Gambit “other variations,” deflection refers to tactical moments where White’s sacrifice (typically starting with 1.d4 d5 2.e4) forces Black’s key defender to leave an important square. The defining feature is that the gambit’s pressure on the center and the c-file/diagonal often creates a moment where a defender must respond, enabling a follow-up like a fork, capture, or winning tempo.
