Learn How to Win Material: Knight Fork
This chess puzzle comes from the Sicilian Defense, Smith-Morra Gambit Accepted, where White uses active pieces and king safety to create a forcing tactical shot. The key idea is a knight fork against the exposed black king and a valuable rook, turning development and piece activity into a decisive material gain. In positions like this, the side with the safer king and more active minor pieces can punish an uncastled king very quickly, especially when a central defender is overloaded or undefended.
