Learn How to Spot Mate in 1: King Safety
This puzzle is a classic example of king safety deciding the game in one move. White’s pieces are already aimed at the enemy king, and the key idea is to notice that the king has no safe flight squares and no piece can interpose or capture the attacking queen. In practical chess, these positions often look balanced until you scan for forcing checks. When the opponent’s king is boxed in, a single forcing move can end the game immediately.
