John Higgins still has it all to do after fighting back to 4-4 after losing the first three frames in his quarter-final against Mark Selby.

Breaks of 118, 124 and 117 gave Selby the early initiative, but the Scot responded with four frames of his own, including a run of 141 in the seventh.

World number four Selby then struck back in the last to level the match.

Meanwhile, seven-time champion Stephen Hendry trails Shaun Murphy 9-7, despite hitting a 147 seventh-frame break earlier in the day.

And Australia's Neil Robertson made an assured start and led world number two Stephen Maguire 5-3 in the other match.
