Three Knights Opening Steinitz Rosenthal Variation Puzzle (Rated 929): Win a Fork — Decisive Material Gain

This middlegame puzzle shows how a forcing check can expose loose coordination and create a winning fork-style tactic. White’s queen is active near the black king, while Black’s back rank and queenside pieces are awkwardly placed. The key idea is to use tempo: a forcing move that checks the king can also pull it away from defending important material. In classical chess, these tactical shots often decide positions where one side is already ahead in activity and king safety.
