Learn How to Win with a Fork: London System Tactic
This middlegame puzzle comes from the London System and shows how a single tactical shot can flip the evaluation. White’s pieces are active, but the real idea is to exploit the opponent’s king safety and loose coordination. When a knight or queen is overextended, a forcing check can create a fork-like sequence that wins material and keeps the initiative. In classical chess, these short tactical wins often appear when development is uneven and the king is still vulnerable.
