"We all know how to play checkers. Many fewer of us know how to play a complex version called “pool checkers,” because the game was defined in our lifetimes by small pockets of African-American men around the South. This variation on checkers turns a simple child’s game into a fierce, intellectually challenging sport with the complexity of chess. And its masters — the men who have dominated the game nationally for years — congregate almost daily in a little shotgun house in Vine City, a neighborhood just west of downtown Atlanta. Learn about and hear the voices of men — with nicknames like “Concrete” and “Iron Claw” — who made the South dominant in yet another sport. It just happens to be a sport you’ve never heard of."
