TBILISI (Reuters) - The world's first female chess grandmaster, Nona Gaprindashvili, has filed a $5 million defamation lawsuit against Netflix over a line in its "The Queen's Gambit" series which her lawyers say is false and sexist.

The 80-year old Soviet chess icon, a hero in her native South Caucasus Republic of Georgia, was described in the show's last episode as a female champion who had "never faced men".
