Krishnan Sasikiran (Black) Puzzle: Fork — Win Material
A fork is a tactical move that attacks two or more targets at once, often combining check with an attack on a valuable piece. In this position, White’s queen uses the exposed black king to gain a tempo while also targeting an active rook. The tactic is especially powerful because Black’s king has limited safe squares and the rook cannot escape effectively. Although Black is materially ahead, White’s king-safety advantage and tactical coordination create a decisive material gain.
