Learn How to Spot: Mate in 1
This puzzle is a classic middlegame mating pattern built around an advanced pawn and king safety. White’s passed pawn on the h-file is one step from promotion, but the real point is that it delivers immediate checkmate because the black king has no escape squares and the position is already overloaded by tactical weaknesses. In classical chess, these one-move finishes often come from forcing geometry rather than material count.
