Learn How to Spot a Mate in 1: King Safety
This puzzle comes from a sharp middlegame in the King's Indian Defense, where king safety matters more than material. White’s king is still stuck in the center, and Black’s pieces are coordinated around the vulnerable kingside. In positions like this, one forcing move can end the game immediately if the defender has no useful interposition or capture. The key lesson is to always check for direct mating threats before considering quieter strategic plans.
