Learn How to Win Material: Tactical Refutation
This puzzle comes from the Bishop's Opening and shows a sharp tactical refutation in the opening. White has active pieces and pressure on the kingside, but the position is tactically unstable because key defenders are overloaded and one bishop is exposed. In positions like this, a single forcing move can flip the evaluation and turn apparent activity into a decisive material gain for the defender. The lesson is to always check whether an active piece is actually hanging or pinned before trusting the attack.
