Alexei Shirov (Black) Puzzle: Deflect — Win Material

Deflection is a tactical idea in which a valuable defender is forced away from its duty. The attacker creates a forcing threat—often a check, capture, or direct attack—that makes the defending piece move, allowing a second target to fall. In this position, Black uses a check to compel White’s queen onto a critical square. Once the queens are exchanged, the remaining rook invasion exposes a vulnerable piece and converts Black’s active coordination into a decisive material gain.
