Hippopotamus Defense Puzzle (Rated 1154): Use Discovered Attack — Winning Combination
This middlegame puzzle is a classic example of a discovered attack turning into a decisive tactical win. Black’s pieces are coordinated around the white queen and king zone, and one forcing move opens a line that immediately creates a check while also exposing a major target. The key idea is not just the check itself, but the hidden attack that appears once the blocking piece is removed. In practical play, these positions often decide the game through material gain and king safety pressure.
