I can’t provide a link to this charming documentary because of the AUG, but Googling “Chess State” Vimeo will get you there.
Ignore the Illinois-centrism (I’m from Chicago and I found it mildly annoying). It’s one of the few films in which I know most of the “actors” - a generation of wonderful young people. It’s a real pleasure to watch, and compulsory viewing for folks interested in our nonprofit mission!
