Ruy Lopez Lucena Variation Puzzle (Rated 1395): Win Material — Fork Tactics
This middlegame puzzle shows how a single active queen can create a decisive material gain by combining check with a fork-like attack on loose pieces. Black’s queen invasion is not just a forcing move; it also exploits the coordination of White’s minor pieces and the vulnerable back rank around the king. In classical chess, these tactical shots often arise when one side has better piece activity and the opponent’s pieces are overloaded or pinned.
