 Crucible curse

The "Crucible curse" (also known as "The curse of the Crucible" or sometimes the "Crucible jinx") refers to the fact that no first-time snooker world champion has retained the title the following year since the tournament moved to the Crucible Theatre, Sheffield in 1977.The last player to successfully defend his first world title was John Pulman in 1964, when the championship was still decided by challenge matches, and before the tournament relocated to the Crucible Theatre.
