The 1985 World Snooker Championship final, also known as the black-ball final, was played on the weekend of 27–28 April 1985 at the Crucible Theatre in Sheffield, England. The final of the 1985 World Snooker Championship was between defending world champion Steve Davis and 1979 runner-up Dennis Taylor. It was Davis's fourth appearance in a final and Taylor's second. The best-of-35-frame match was split into four sessions. Davis won every frame in the first session to lead 7–0 and extended his lead to 9–1 in the second session but led 9–7 overnight and 13–11 after the third sessions. Until the match was over, Taylor was never ahead in frames but had tied the contest three times at 11–11, 15–15 and 17–17. The deciding frame culminated in a number of shots on the final black ball. After both players had failed to pot it several times, Taylor potted the black to win his only world championship. Media outlets reported this as a major shock: Davis had been widely predicted to win the match, having lifted three of the previous four world championship titles.
