The TV series “Queen’s Gambit” is a story of a female character who grows up to be a world class chess player. The story is of a smart girl with troubled childhood who discovers chess while at boarding school which prepares children for adoption.
From the “frying pan” of troubled parents, to being mentored into chess at a boarding school and then “into fire” of dysfunctional family who adopted her, is a perfect bell curve for a story. Chess is just a prop. The traverse of the character through age and various influences is the main plot.
It’s a seven part, one hour each, episodes which will drive you to download a few chess apps and try the game, at least for few hours. The story mentions a lot of chess moves and books none of which I found compelling after few minutes of perusals. But the series is bing worthy.
