King's Gambit Decoy Into Pin Chess Puzzles

The King's Gambit Decoy into Pin is a tactical motif where a sacrifice in the King's Gambit lures a key defender onto a square that becomes vulnerable to a pin. In the classic opening structure after 1.e4 e5 2.f4, White often uses the f-pawn advance or a capture on f5 to pull a piece away from the king's defense, then pins it against the king or queen with a bishop, rook, or queen. The defining feature is the bait-and-pin sequence: first decoy, then a line-opening pin on the e-file, f-file, or diagonal toward the black king.
