Learn How to Mate in 1: King Safety
This middlegame puzzle is a classic king-safety finish: White’s queen and knight have already created a mating net around the black king. The key idea is that the king’s pawn shield is weakened, so one forcing move ends the game immediately. In positions like this, the strongest tactic is often not a material win but a direct checkmate when the enemy king has no escape squares and no piece can interpose or capture the attacker.
