Four Knights Game Hanging Piece Chess Puzzles

The four knights game hanging piece is a tactical motif in the Four Knights Game where one side leaves a piece undefended or only barely defended after the opening develops with moves like 1.e4 e5 2.Nf3 Nc6 3.Nc3 Nf6. In this structure, a knight, bishop, or even queen can become a hanging piece if it is placed on a central square without enough support. The key feature is that the position is still in the opening, but one piece is already tactically vulnerable.
