Learn How to Mate in 1: Modern Defense Trap
This puzzle comes from the Modern Defense and shows how a single tactical shot can end the game immediately. The key idea is to recognize when the opponent’s king is exposed and the board geometry allows a direct mating net. In positions like this, active pieces and weak king safety matter more than material. Even in the opening, a well-placed knight can create a forced finish if the king has no escape squares and the checking piece is protected.
