Mate In 2 Puzzle (Rated 1280): Force Mate in 2 — Bishop & Queen
This chess endgame puzzle is a classic example of forcing the king into a mating net with coordinated bishop and queen activity. The key idea is to use a forcing check that drags a defender onto a critical square, opening the final line for a decisive finish. Even though the position looks tactical rather than purely technical, the lesson is the same: active pieces, open files, and king safety matter more than material when a mate is available.
