Learn How to Spot a Fork: London System Tactic
This London System puzzle is a classic middlegame tactic where active queen play creates immediate threats against the king and loose pieces. The key idea is to use a forcing check to pull the enemy king into an awkward square, then win material by attacking multiple targets at once. Even when White appears materially ahead, king safety and piece coordination can override static evaluation. In classical chess, these tactical shots often decide the game before any endgame becomes relevant.
