A giant chess set that had to be played on to get past
- "They were standing on the edge of a huge chessboard, behind the black chessmen, which were all taller than they were and carved from what looked like black stone. Facing them, way across the chamber, were white pieces — the towering white chessmen had no faces."

On 4 June 1992, Harry Potter, Ron Weasley and Hermione Granger were attempting to prevent the theft of the Philosopher's Stone by a servant of Lord Voldemort that, at the time, they believed was Severus Snape. After making their way past the Stone's first three defences, they encountered this obstacle in the fourth chamber. Ron took command of the black side, with himself, Harry, and Hermione replacing missing pieces, in order to defeat the obstacle and be allowed to pass. In the end, Ron sacrificed himself to the white Queen to allow Harry to checkmate the opposing King.
At the end of year feast, Albus Dumbledore awarded Ron fifty house points for "the best played game of chess that Hogwarts has seen these many years". Percy Weasley proudly boasted about his brother's accomplishment.
Behind the scenes
- In the film adaptation of Harry Potter and the Philosopher's Stone, Ron is actually riding the black knight instead of just taking its place on the board.
- In LEGO Harry Potter: Years 1-4, Ron trips over a chess piece's sword, falls unconscious, and is unable to follow his friends.
- The filmmakers used radio and digital effects to create the movement of the giant chess pieces in Harry Potter and the Philosopher's Stone (film). The explosive effects were created using compressed air. Ronald Weasley actor Rupert Grint states "I've actually still got a broken piece of the horse!"
