RéTi Opening Trapped Piece Chess Puzzles

A Réti Opening Trapped Piece is a motif where a piece, usually a knight or bishop, becomes stranded after White starts with 1.Nf3 and aims for flexible control of the center. The defining feature is that the Réti’s flank development and delayed central commitment can lure an opponent’s piece onto a square where it is later boxed in by pawns or minor pieces.
