Learn How to Win with a Fork: Accelerated London System
This puzzle comes from the accelerated London system in the queen’s pawn game, where development and piece activity matter more than slow pawn grabbing. White has a big lead in mobilization, and that creates tactical chances against an exposed queen and an uncastled king. The key idea is to use a forcing move that checks the king while also creating a fork on a loose major piece. In practical classical chess, active pieces often outweigh extra material when the opponent’s king is still in the center.
