RéTi Opening Sacrifice Chess Puzzles

The Réti Opening Sacrifice is a motif in the Réti Opening where White gives up material, usually a pawn or exchange, to exploit rapid development, central control, or a weakened king position. A defining feature is the flexible 1.Nf3 followed by a delayed central strike, often with c4, g3, or d4, where the sacrifice opens lines for the pieces.
