Elizabeth "Beth" Harmon played by Anya Taylor-Joy
BIOGRAPHY
Sole Survivor
Beth Harmon was born on November 2, 1948 in Winchester, Kentucky, United States to mother Alice, who earned a Ph.D. in mathematics from Cornell University, and father Paul, who is largely absent from Beth's childhood. Alice separates from Paul with Beth in her custody and experiences a severe decline in her mental health, eventually leading to her intentionally causing a car crash. Beth is the sole survivor of the crash and is sent to live at Methuen Home, an exclusively-female Christian orphanage.
Life at Methuen
At Methuen, Beth befriends one of the girls, Jolene, who advises that she take the home's state-mandated tranquilizers at night. While running errands in the home's basement, Beth discovers the home's custodian, Mr. Shaibel, playing chess by himself, and eventually convinces Shaibel to teach her the game. At night, under influence from the drugs, Beth is able to visualize chess games on the ceiling, allowing her to quickly develop an unusual aptitude for the game. Shaibel introduces Beth to a local high school chess club facilitator, who is impressed with her command of the game and invites her to a simultaneous exhibition against the entire high school club. Beth handily defeats all her opponents, and Shaibel gives her a book introducing her to advanced chess theory. Beth develops an increasingly severe dependency on the tranquilizers during her early years at Methuen, and is prohibited from playing chess after an overdose.
The Wheatley's
At age 15, Beth is adopted by Allston and Alma Wheatley of Lexington, Kentucky. Beth begins siphoning her adoptive mother's tranquilizer pills, which aid in her renewed commitment to chess. With financial assistance from Shaibel, Beth enrolls in the local high school chess tournament, where she ultimately defeats state champion Harry Beltik, partially with the aid of the pills. Beth also develops a crush on one of her opponents, an older boy named D.L. Townes. Though Beth's adoptive father Allston leaves the family, she and Alma decide to support themselves via prize money from subsequent chess tournaments.
Tournaments
Starting with Beth's victory at a Cincinnati tournament, she agrees to give 15% of her earnings to Alma as a management commission. The two spend months traveling the country for tournaments, elevating Beth to a national chess icon profiled in major magazines. At the 1966 Las Vegas US Open, Beth reunites with Townes, now a journalist, and the two share an intimate moment before being interrupted by a man Townes is living with; Beth rebuffs Townes before he can offer an explanation. At the tournament, Beth meets Benny Watts, a fellow prodigy who enjoys notoriety in chess circles. She experiences her first loss against him the next day, leading the two of them to finish the tournament in a tie for first place. Around this time, a begins to consume alcohol at an increasing rate, and introduces Beth to beer and liquor.
Beth's next major tournament is in Mexico City, by which point Alma's alcoholism has become severe. Beth competes against various international players, but loses against the Soviet world champion, Vasily Borgov. After the match, she finds that Alma has died of hepatitis owing to her alcohol abuse. Allston leaves the Wheatley estate in Beth's possession for the time being; back in Kentucky, she reconnects with Beltik, who offers to train her. Beth invites Beltik to live in the house with her, and the two spend time training and share a short-lived romance before Beltik amicably parts ways with her, having taught her all he can and knowing that her commitment to chess dashes the possibility of a long-term relationship.
US Championship
In 1967, Beth attends the US championship, where she once again faces off with Benny. The two become closer friends during informal games of speed chess that Beth uses as training despite consistently losing; the following day, she quickly defeats Benny in the final round. Benny invites Beth to live with him in New York to train for the international championship in Paris later that year, where Beth sobers up and begins a sexual relationship ith Benny. The night before her match with Borgov in Paris, Beth has a drunken one-night stand with a woman introduced to her by Benny, and the following morning loses again to Borgov while hungover.
End Game
Beth returns to Lexington and personally buys Allston's house from him; she spends the next several days engaged in an extreme drug and alcohol binge until her childhood friend Jolene visits her for the first time since leaving the orphanage. The two attend Shaibel's funeral, and Beth revisits the orphanage, where she discovers that Shaibel has followed her career all along. Jolene loans Beth the money necessary to cover her participation in the prestigious Moscow invitational. Beth's final match is with Borgov, which is adjourned after 40 moves. Beth rekindles her friendship with Townes, who is covering the match, and receives extensive consultation and support over the phone from Benny, Beltik and other friends she has made from the chess scene, who have assembled a team to help analyze her adjourned game with Borgov. That evening, Beth finally defeats Borgov and wins the tournament.
