Dutch Defense Semi Leningrad Variation Puzzle (Rated 1465): Use Discovered Check — Winning Material

This puzzle is a classic middlegame example of discovered check leading to a decisive material gain. Black’s active pieces coordinate against the white king and queen, while White’s extra material is offset by loose pieces and a vulnerable king zone. The key idea is to open a line so one piece gives check while another piece simultaneously attacks a valuable target. That kind of forcing sequence often turns a slight initiative into a winning combination.
