Rapport Jobava System Puzzle (Rated 1379): Win Material — Decisive Middlegame Tactics

This puzzle is a classic middlegame example of tactical pressure turning into a decisive material gain. White’s pieces are active, but the key is that Black’s queen and king are awkwardly placed, creating tactical targets on central and queenside squares. The winning idea comes from exploiting a strong knight outpost and forcing the opponent’s queen into a passive role, after which a direct check becomes possible. It is a good example of how activity and coordination can outweigh a temporary material deficit.
