"The Queen's Gambit" is a fictional story based on the novel of the same name by Walter Tevis. While the character of Beth Harmon and her journey to become a chess prodigy are not based on a real person, the series incorporates elements of real chess history and culture. The show's portrayal of chess, along with its themes of addiction and personal growth, resonates with many, but it remains a work of fiction rather than a true story.

As of now, there is no Season 2 of "The Queen's Gambit." The show's creator, Scott Frank, has indicated that it was intended as a limited series, focusing on the complete story of Beth Harmon. While it received widespread acclaim and has generated interest for more content, Frank has stated that he feels the story is complete as it stands. Therefore, it is unlikely that a second season will be produced.

Netflix was sued over "The Queen's Gambit" by a chess player named Borgov, who claimed that the series' portrayal of a character inspired by him infringed on his rights. He argued that the show used his likeness and personal story without permission, alleging that it caused him emotional distress and harmed his reputation. The lawsuit highlighted concerns over intellectual property and the portrayal of real-life figures in fictionalized narratives. However, the case raised complex legal questions about artistic interpretation and the boundaries of biographical representation.

In "The Queen's Gambit," the green pills that the protagonist, Beth Harmon, takes are a fictional representation of tranquilizers or sedatives. They are used to help her manage anxiety and stress, especially as she navigates the pressures of competitive chess. The pills symbolize her struggles with mental health and addiction, reflecting the broader themes of the series, including the impact of trauma and the quest for personal success amidst personal challenges.
