Sicilian Defense Open Puzzle (Rated 985): Fork — Win Material

A fork is a tactical pattern in which one piece attacks two or more valuable targets at once. In this middlegame position, White can exploit an overloaded defensive setup and use an active knight to create a decisive material gain. The key idea is to recognize that a pinned or attacked piece may still have a powerful tactical function. Strong piece activity, an exposed defender, and an undefended target combine to make the fork especially effective.
