RéTi Opening Deflection From Fork Chess Puzzles

Réti Opening Deflection from Fork is a tactical motif in the Réti Opening where one move forces a defender or king-side piece away from its key square, creating a fork threat on the next move. The defining feature is a deflection that clears a line or weakens coordination so a knight, queen, or bishop can attack two targets at once. In practical terms, it often appears after White develops with Nf3 and c4, then uses a forcing move to pull a piece off a critical square.
