Learn How to Trap a Piece: Italian Game Theory
This Italian Game puzzle shows how a seemingly active piece can become trapped when the king’s shelter is weakened and the back rank is vulnerable. White’s pieces are coordinated around the enemy king, and the key idea is to exploit the overloaded defender on the h-file. The position is a classic middlegame example of tactical refutation: one forcing move creates a direct threat that wins material by exposing a trapped piece and removing the defender of the king’s escape square.
