Wu and Allen produced a session of spellbinding snooker and finished locked at 11-11 to perfectly set up the final session of their last-four meeting.

Resuming at 7-7 on Saturday, the third session of the match was a complete contrast to their epic slugfest on Friday, that produced the longest frame ever played at the famous venue.

China’s Wu set the tone, opening with a sublime 142 and also constructing breaks of 76 and 121 to lead 10-8 at the mid-session interval.

However, Allen, who is attempting to become the first player from Northern Ireland to reach the final since Dennis Taylor in 1985, showed he had also thrown off the shackles of negativity.

The 40-year-old enjoyed a run of 56, and well-crafted breaks of 85 and 99 enabled him to draw level at 10-10.

Wu, 22, who defeated Lei Peifan, Mark Selby and Hossein Vafaei to reach the last four, responded with 140, his third century of the day.

But as the tension increased, in what felt like an important concluding frame to the session, Wu was unable to capitalise after getting the first opportunity.

That allowed Allen, who could become the oldest first-time winner at the Crucible, to make a couple of useful contributions and ensure there was nothing to divide the pair.

They return to play the final session of their best-of-33 encounter at 19:00 BST on Saturday, with a possible 11 frames still to get through, as they attempt to set up a title match against Murphy.
