Chess, according to the official Royal Albert Hall website, "involves a romantic triangle between two players in a World Chess Championship, and the woman who manages one and falls in love with the other. Although the protagonists were not intended to represent any specific individuals, the characters' personalities are loosely based on those of Victor Korchnoi and Bobby Fischer."

The Benny Anderson-Tim Rice-Björn Ulvaeus musical Chess debuted on the London stage with a cast led by Elaine Paige, Tommy Körberg and Murray Head, while the short-lived Broadway company featured Judy Kuhn, Philip Casnoff and the late David Carroll. The score includes such tunes as "Nobody's Side," "One Night in Bangkok," "Anthem," "I Know Him So Well," "Pity the Child" and "You and I." The original Broadway cast recording was released on RCA Victor.
