In snooker, the "Crucible Curse" refers to the fact that no first-time winner of the World Snooker Championship has successfully defended his title since the event was first held at the Crucible Theatre in Sheffield in 1977. Of the 18 first-time champions in this era, only two have even made the final the following year, and six were eliminated in their first match. The "curse" can even be seen in the pre-Crucible era—the three first-time champions between the start of the championship's "modern era" in 1969 and its move to the Crucible all lost in their respective semifinal matches the next year. All three players went on to win a championship at the Crucible, and all failed to retain their title after their first victory at that venue.
