Semi-final poised at 7-7 after attritional 14th frame

John Higgins edges to 13-11 lead over Shaun Murphy

Wu Yize and Mark Allen’s semi-final is poised at seven frames all after their afternoon session ended with a bizarre frame – the longest in the World Snooker Championship’s Crucible era – clocking in at just over 100 minutes.

Allen began the afternoon trailing 6-2 overnight to an opponent high on confidence and belief, but fought back in style, winning five frames in succession to edge 7-6 ahead.

The session at the Crucible concluded with a remarkable 14th frame, with a cluster of eight reds jammed around the black ball on the edge of a corner pocket. It resulted in a lengthy stalemate, 55 minutes passing without a ball being potted.
