Ponziani Opening Jaenisch Counterattack Intermediate Puzzle (Rated 1130): Win Material — Discovered Attack

This middlegame puzzle shows how a discovered attack can turn a tactical position into a decisive material win. White’s pieces are coordinated around the enemy king, and one forcing capture opens the line for a stronger follow-up. The key idea is that a checking move can also uncover a second threat, creating a double problem for the defender. In classical chess, these motifs often decide games by winning a major piece or exposing the king.
