Task: Question Answering
Input (English): Passage: Set in 2003, Huck Cheever is a young and talented poker player in Las Vegas haunted by his relationship with his estranged father, L.C. Cheever, a two-time World Series of Poker Champion. Huck is a regular in Vegas poker rooms but needs $10,000 to get a seat in the World Series of Poker Main Event.
After a good night at the Bellagio hotel's poker room, Huck goes to a party and meets aspiring singer Billie Offer, who has just arrived in town. Billie's older sister Suzanne warns her that Huck is "hustle 10, commitment zero." Back at the Bellagio, Huck is doing well at the tables before L.C. returns to town from the South of France. Huck greets his father coldly. The two play heads-up.
Loan shark Roy Durucher tells Huck that he plays poker as well as anybody, except for his reputation as a "blaster" (not patient enough) who always goes for broke. Roy proposes to stake Huck in the $10,000 main-event with a 60% — 40% split of any winnings, but Huck refuses. After failing to borrow money from his friend Jack, Huck goes to Suzanne's place hoping for a loan. Instead he runs into Billie, who gets a call confirming that she has landed a job singing at a club.
Huck proposes a celebration and at Binion's Horseshoe he shows her how to play poker. L.C. arrives and shows Huck a wedding ring of Huck's late mother's that Huck had pawned and that L.C. has redeemed. Huck loses his winnings. Over dinner, he explains to Billie that his father stole from his mother before leaving her. Huck says his father taught him how to play on the kitchen table with "pennies, nickels, and dimes." They make love after dinner. As Billie sleeps, Huck steals money from Billie's purse. 
Question: What are the full names of the two people who play heads-up?
Output (English): L.C. Cheever.
