Learn How to Mate in 3: Kingside Attack
This classical chess puzzle is a model of a kingside attack where active pieces outweigh raw material. Even though White is down materially, the attacking pieces coordinate to exploit a weakened king shelter and a pinned defender. The key idea is to create a forcing sequence with check, then use the rook and knight to remove the last defender around the king. In middlegame tactics, initiative often matters more than countable material.
