Il Vaticano
Published August 15, 2026
Il Vaticano is a fake chess special move invented as a hoax by the /r/AnarchyChess subreddit in December 2022, where two same-colored bishops flanking two enemy pieces swap positions and capture the pieces between them. It became a running gag on the subreddit alongside its long-standing en passant jokes.
Overview
Il Vaticano is a made-up chess move popularized by the /r/AnarchyChess subreddit. The supposed rule lets two same-colored bishops sitting on the same rank or file with two enemy pieces between them swap places and capture both middle pieces in a single move1. It does not exist in official chess rules and was invented purely as an in-joke.
The bit works because /r/AnarchyChess regularly leans on the real but obscure en passant pawn capture to bait newcomers, so bolting a fake bishop equivalent onto the same graphic feels plausible at a glance2. Screenshots of boards set up for Il Vaticano started circulating beyond the subreddit within days of the first post3.
Origin & Background
Redditor /u/MidnightFireworks kicked off the joke on December 20, 2022 with a post to /r/AnarchyChess showing normal and 'special' moves for each chess piece1. The pawn's special was the real en passant, while the bishop's special was the newly invented Il Vaticano. The graphic pulled over 7,000 upvotes within about a month3.
How It Spread
How to Use This Meme
The joke typically works one of two ways. People either post a chessboard mid-Il Vaticano and treat it as a straight rules question, or they drop the move into wider chess drama posts as if it decided a real game. Urban Dictionary's example entry runs with this, using a fake line about 'Hans Niemann used Il Vaticano against Magnus Carlsen'8.
