Learn How to Spot a Double Check: Mate in 2
This chess endgame puzzle is built around a forcing double check, one of the most powerful tactical motifs in classical chess. When a king is exposed and its escape squares are limited, a checking move that attacks with two pieces at once can leave the defender almost no practical choices. In positions like this, the key is not material count but king safety and coordination. The attack works because the checking piece also opens a second line of pressure, creating a mating net.
