French Defense Horwitz Attack Deflection in Chess

In the French Defense Horwitz Attack, “deflection” is a tactical idea where White plays a move that lures or forces a Black defender away from an important square or line. A defining feature is the Horwitz Attack setup with White’s queenside pressure and a tactical target around Black’s central/dark-square control, often involving a key piece that must guard a follow-up threat. The deflection enables a winning tactic—commonly by opening a line, winning material, or creating an immediate attack.
