Four Knights Game Scotch Variation Accepted Hanging Piece in Chess

In the Four Knights Game Scotch Variation (Accepted), the line typically arises after 1.e4 e5 2.Nf3 Nc6 3.Nc3 Nf6 4.d4 exd4 5.Nxd4, where Black accepts the Scotch by capturing on d4 and the position opens quickly. The “accepted hanging piece” motif means one side can allow (or force) a piece to become temporarily loose—often a knight or pawn—so it can be won with tempo or a tactical follow-up.
