Indian Defense London System Discovered Attack Beginner Chess Puzzles

In the Indian Defense London System, a discovered attack usually appears when a piece moves away and opens a line for another piece to attack a target. A common beginner-friendly version is when a bishop, knight, or pawn shifts and suddenly the queen, rook, or bishop behind it becomes active on the same file, diagonal, or rank. In this opening structure, the tactic often starts from a London-style setup with White's bishop on f4 and Black developing in an Indian Defense formation.
