Russian Game Mate In 1 Chess Puzzles

Russian game mate in 1 refers to a one-move checkmate that appears in positions from the Russian Game, also known as the Petrov Defense, after 1.e4 e5 2.Nf3 Nf6. The key feature is that Black has developed the knight to f6 and the position has become tactically vulnerable, often because the king is exposed and a direct mating move is available.
