Videogate?

Fabiano Caruana has had the best of the opening battles so far in his world championship match with Magnus Carlsen, but that may come to a screeching halt. Apparently someone royally screwed up, whether on his team or on the St. Louis Chess Club staff - or both. Some of Caruana's preparation was apparently shown during a promotional video, and while it was soon taken down it wasn't taken down soon enough for that information to get out to the wider public, and ultimately to team Carlsen as well. Uh oh.
