RéTi Opening Decoy Into Pin Chess Puzzles

The Réti Opening Decoy into Pin is a tactical motif that can arise from the Réti move order, usually after 1.Nf3 and a flexible c4 or g3 setup, when White lures a black piece onto a square where it becomes pinned. The key idea is the decoy: a move invites a defender to capture or occupy a line, and that piece then gets pinned to a king, queen, or valuable piece by a bishop, rook, or queen.
