Learn How to Spot a Mate in 2: Bishop Sacrifice
This middlegame puzzle comes from the Philidor Defense and shows a classic attacking pattern against an exposed king. White uses a bishop sacrifice to drag the black king into the open, where the queen can deliver a forced finish. The key idea is not material gain, but king safety: once the defender is removed and the king is displaced, the remaining pieces coordinate for a direct mating net. This is a strong example of a short tactical combination in classical chess.
