Rapport Jobava System With E6 Puzzle (Rated 1158): Win Material — Tactical Refutation
This middlegame puzzle is a classic example of a tactical refutation built around king safety and loose pieces. Black’s queen and knight coordinate to create a forcing attack against the white king, which is still stuck in the center. The key idea is that an apparently active white position hides tactical weaknesses: a hanging piece, weak dark squares, and an overloaded defense. When the attack starts, White is forced into a narrow defensive path that leads to a decisive material gain for Black.
