Learn How to Win Material: Bishop Sacrifice
This middlegame puzzle comes from the Philidor Defense and shows a classic attacking idea: using a bishop sacrifice to open lines around the enemy king. White’s pieces are coordinated well enough to create immediate tactical pressure, even though Black appears materially ahead. The key is that the queen and bishop work together to exploit the king’s shelter and force a response that changes the evaluation. This is a strong example of a tactical refutation in classical chess.
