Learn How to Spot Mate in 1: King Safety
This middlegame puzzle is a pure king-safety lesson: White’s pieces are already aimed at the enemy king, and the final blow comes from a direct mating net. The key idea is to notice when the opponent’s king has no flight squares, no useful blocks, and no capture that can remove the threat. In classical chess, these positions often look balanced materially, but one forcing move ends the game immediately because the king is boxed in by its own pieces and pawns.
