Four Knights Game Glek System Discovered Attack in Chess

In the Four Knights Game Glek System, a discovered attack happens when one piece moves away to reveal a line to the enemy king or a high-value piece. A defining feature is the Glek-style setup that often places a rook, bishop, or queen behind a piece that can later “unmask” an attack with tempo. For an intermediate player, the concept is about timing that unmasking move so the revealed threat is immediate and tactically decisive.
