Learn How to Spot Mate in 1: Discovered Check
This middlegame puzzle is a classic example of a forcing tactical finish where the king is left with no safe squares and no useful defense. The key idea is a discovered check that also creates a double-check effect, which is especially powerful because it limits the opponent’s responses to only king moves. In positions like this, material balance matters less than king safety and piece coordination. When the enemy king is boxed in, a single forcing move can end the game immediately.
