Sicilian Defense Open Puzzle (Rated 1150): Fork — Win Material

A fork is a powerful tactical pattern in which one piece attacks two or more targets at once. The strongest forks often begin with check, forcing the opponent to respond while the attacking piece creates a second threat. In this middlegame position, Black uses a knight to invade a vulnerable square near the king, exploiting the queen’s exposed placement and the tension around the kingside. The result is a decisive material gain and a clear example of how forcing moves can overturn an apparently active position.
