Learn How to Win Material: Fork Tactic
This puzzle shows a classic tactical refutation in the middlegame, where a forcing check creates immediate problems for the opponent’s queen and rook coordination. In the Accelerated London System, even a seemingly active queen can become vulnerable if it is overextended and tied to a pinned piece. The key idea is to use forcing moves to exploit a loose back rank and a piece that cannot move freely because it protects something more valuable.
