Queen's Gambit Accepted Puzzle (Rated 851): Fork — Win Material

A royal fork is one of the most powerful tactical patterns in chess: a single piece attacks the king while also targeting valuable material. The check forces a response, giving the attacking player time to collect the second target. In this middlegame, White’s active knight and bishop create strong pressure around the black king, while Black’s queen becomes vulnerable to a forcing knight jump. The result is a decisive material gain, even though the position begins with equal material.
