Il Vaticano

Il Vaticanorefers to ahoaxorchestrated by thesubreddit/r/Anarchy Chess, where participants discuss and make memes about a special move named "Il Vaticano." The supposed special move involves two bishops flanking two chess pieces on either side and switching positions with each other as a means of capturing the middle pieces. The hoax began in late December 2022, with Redditor Midnight Fireworks being the earliest creator to discuss the move on December 20th. The subreddit /r/Anarchy Chess often creates hoax chess moves, sometimes bolstered by the inclusion of the "En Passant," a real although uncommon chess move involving pawns.
