Italian Game Giuoco Piano Pin in Chess

In the italian game giuoco piano pin, White reaches the Giuoco Piano setup (typically 1.e4 e5 2.Nf3 Nc6 3.Bc4) and then uses a pin motif—most often against a piece on the c6 or e5 line—created by the bishop’s alignment. A defining feature is that White’s bishop on c4 (or a related diagonal) restricts Black’s ability to move a pinned piece without losing something important.
