Russian Game Mate In 2 Beginner Puzzle (Rated 990): Mate in 2 — Bishop and Knight Pattern

This puzzle is a forcing middlegame combination built around a classic bishop-and-knight mating pattern. White’s pieces coordinate to exploit the exposed king and the lack of safe squares around it. The key idea is not material gain, but using a forcing check to drag the king into a vulnerable line, where the follow-up becomes unavoidable. Patterns like this often appear in classical chess and in tactical puzzles where piece activity matters more than raw material.
