If you haven't seen this movie, which was partially filmed August 14th through the 18th, 2000 during the Asa Long Memorial ACF 3- Move Nationals Checker Tournament in Toledo, Ohio, click on the link at the bottom of this post.
"At the age of 68, Harold O'Brien met the love of his life and married for the first time. Except when he was drafted into World War II, Harold had never ventured far from his farm and hometown, but Norma convinced him to enter the Iowa state Checkers Championship. With her encouragement and faith, and against very long odds, Harold won the championship. Only a few months later, though, Norma died, and Harold began a six-year struggle with severe depression. At one point, realizing that he was suicidal, he had himself hospitalized. One morning, in his eighty-first year, Harold awoke thinking about how disappointed Norma would have been with his floundering life. In her memory, he decided to enter the National Championships."
The movie is 39 minutes long.
(You'll have to sit through a 30 seconds sponsor's ad before the movie starts, but it's worth it.)
