Learn How to Win Material: Tactical Refutation
This puzzle comes from the Polish Opening and shows a classic tactical refutation in the middlegame. The key idea is that a seemingly active bishop move can be met by a forcing capture that changes the balance immediately. After the first tactical shot, the position simplifies into a sequence where the defender is overloaded and a second piece can be won. It is a good example of how classical chess tactics often revolve around removing the defender and converting activity into material.
