Learn How to Win Material: Tactical Refutation
This puzzle comes from the Bogo-Indian Defense and shows a classic tactical refutation in the middlegame. White has active pieces and a lead in development, but one loose piece and a pinned defender create a tactical target. Black can use a forcing sequence to win material by exploiting the alignment of pieces and the fact that a key white bishop is overloaded. In classical chess, these moments often decide the game because one accurate tactical shot can overturn a small positional edge.
