Qxd4 Puzzle (Rated 884): Mate — Epaulette Mate
An epaulette mate is a checkmate pattern in which the king’s own pieces restrict its escape squares, often creating a boxed-in king. This Slav Defense puzzle is decided by a direct mating threat against a king stranded in the center. The key tactical features include an absolute pin, a skewer, and a vulnerable king zone. Material advantages become irrelevant when the opponent has a forced mate in 1, making king safety the first priority in every middlegame calculation.
