Just watched it over the past week. I enjoyed it immensely. I don't care whether its depiction of chess is realistic. The lead actress is superb in her role. Its depiction of addiction and depression was spot-on with my experience; many of the scenes gave me chills, particularly when the adoptive mother is involved (whether directly or indirectly).

Highly recommended: "The Queen's Gambit", 7-episode miniseries on Netflix.
