The two last four encounters in Sheffield have already been full of drama, controversy and superb snooker, but we could be set for another late finish as Wu Yize and Mark Allen play to a finish this evening.
The two players are locked at 11-11 after three sessions, so there could be up to 11 frames played when the action resumes at 7pm.
The second semi-final has already resulted in some snooker history being made on Friday after an incredible 14th frame, in which eight reds were left covering the black over the bottom right corner pocket, lasted 100 minutes and 21 seconds to break the all-time record for the longest ever frame at the Crucible.

What is the latest ever finish to a World Snooker Championship match at the Crucible?
You have to go back to 1983 for the latest ever finish to a World Snooker Championship match at the Crucible as legends Cliff Thorburn and Terry Griffiths finished their epic second round encounter at 3.51am.
In a match that had earlier featured an historic 147 maximum break from Thorburn in the opening session, the two players didn't resume until 9.15pm after the previous match was another keenly contested clash.
Thorburn had looked set for victory as he took a 12-9 lead, but Griffiths edged two close frames and dominated the 24th to set up a decider.
With just a few hardy spectators left in the crowd, Thorburn regained the initiative and took the deciding frame to reach the quarter-finals.
The 1980 champion would then go on to reach another world final, before losing 18-6 to Steve Davis.
