Viewers can also watch live coverage of both tables at the Crucible via the BBC Sport website and Connected TV. Dedicated streams will be on hand until Thursday, 30 April, when the tournament goes down to a single table.

The BBC is also hosting a festival of live programmes and free events to celebrate the World Snooker Championship across the city of Sheffield. For information on free tickets to these programmes and more, visit the BBC Shows and Tours website.
