Neil Robertson and Mark Selby will meet in a big-ticket semi-final at the Betway UK Championship.
Robertson saw off John Higgins in a deciding frame after the Scot had recovered from 4-1 down in perhaps the stand-out match of this year’s event at York’s Barbican Centre.
Selby then eased through his evening quarter-final against Matthew Selt 6-1 with a top break of 72 to set up a repeat of the 2013 final – won 10-7 by Robertson.
For the second day running Robertson saw his opponent open with a century – Higgins’ 119 the 600th ton of his career –following Stephen Maguire’s 118 in the last 16 clash.
Robertson won a tough second featuring a lengthy ruling over a free ball and an interruption from a butterfly, which twice landed on the table before referee Jan Verhaas removed it.
The Australian went 4-1 up with runs of 106, 59, 71 and 56 and though Higgins made 69 and a pair of 134s en route to 5-5, he missed several chances in the decider and Robertson prevailed.
“The way I started the match was absolutely brilliant, to go 4-1 up, but John being the champion he is shut me out the next couple of frames,” said Robertson.
“It was one of those deciders, I missed a couple, he missed a couple, luckily for me he’s missed a semi-tricky green in the middle. I almost made a meal of it but I’m very relieved to get through.”
Leeds potter David Grace fought back from 5-1 down to level at 5-5 with Martin Gould in a thrilling match last night
The winner is due to meet Liang Wenbo, whose match against Marco Fu also went to a deciding eleventh frame.
Asked if he can go on and win the tournament, Liang said: “Of course. Everybody has got a chance, you need to be ready.”
