Learn How to Win Material: Accelerated London System
This puzzle comes from the opening phase of a Queen’s Pawn Game and shows how quickly a small tactical detail can decide the game. White has active pieces, strong central influence, and a lead in development, but the position also contains loose pieces and an overloaded defender. In classical chess, those imbalances often matter more than long-term plans. The key lesson is to look for forcing moves that convert activity into material, especially when a piece is pinned, hanging, or tied to multiple defensive jobs.
