Learn How to Mate in 1: Back Rank Mate
This chess endgame puzzle is a classic one-move finish built around king safety and a cramped back rank. White’s heavy piece activity combines with the black king’s exposed placement to create an immediate mating net. In classical chess, these positions reward players who notice when the enemy king has no flight squares and the line to the king is unobstructed. The key idea is to use a forcing move that ends the game at once, rather than winning more material.
