Learn How to Spot a Mate in 1: King Safety
This puzzle is a pure mating finish in a middlegame, where king safety matters more than material. White’s king shelter is weakened, and Black’s pieces are already coordinated around the enemy king. In positions like this, the winning idea is often a forcing check that leaves the king with no escape squares and no useful interposition. When the board is crowded, even a single open line or vulnerable square can decide the game immediately.
