Slav Defense Three Knights Variation Beginner Puzzle (Rated 887): Win Material — Queen Fork

This puzzle comes from the Slav Defense and shows a classic queen fork in the opening. White’s queen jumps into an active square with tempo, creating a direct check while also attacking a loose piece. The key idea is that the opponent’s king is still uncastled and the pinned knight cannot move freely, so one forcing move wins material. In classical chess, these tactical shots often decide the middlegame before development is complete.
