Learn How to Spot Mate in 2: Queen Sacrifice
This chess endgame puzzle is a classic tactical refutation where the attacking side uses a queen sacrifice to force the enemy king into a mating net. The key idea is not material count, but king safety: once the king is dragged onto a vulnerable square, the remaining pieces coordinate to deliver a forced finish. In classical chess, these short combinations often appear when one side has an exposed king, loose back-rank squares, or a piece that can be removed with tempo.
