Chess is a musical with music by Benny Andersson and Björn Ulvaeus of the pop group ABBA, lyrics by Ulvaeus and Tim Rice, and book by Rice. The story involves a politically charged, Cold War-era chess tournament between two grandmasters, one American and the other Soviet, and their fight over a woman who manages one and falls in love with the other. Although the protagonists were not intended to represent any real individuals, the character of the American grandmaster was loosely based on Bobby Fischer, while elements of the story may have been inspired by the chess careers of Russian grandmasters Viktor Korchnoi and Anatoly Karpov.
