Learn How to Spot Mate in 1: Queen Sacrifice
This middlegame puzzle comes from the Philidor Defense and shows how king safety can outweigh material. White’s pieces are ideally placed to exploit the loosened black king shelter, with the queen and knight coordinating around the enemy king zone. Even though Black is materially ahead, the position is tactically lost because the king has no flight squares and key defenders are overloaded or trapped. In classical chess, these are the moments where a forcing attack ends the game immediately.
