Ronnie O'Sullivan endured a birthday to forget as the reigning world snooker champion crashed out of the UK Championship on Thursday after a 6-4 quarter-final defeat against Stuart Bingham.
Bingham will face world number one Neil Robertson in the semi-final after the Australian beat Stephen Maguire 6-2.
Robertson made a superb 128 in frame six but otherwise struggled once more with conditions on table two.
"Once again the table's just absolute garbage today, it's unplayable," Robertson said.
"I'm just glad they're taking it out of the arena now and we're getting down to the one-table set-up and we'll be playing on the main TV table.
"It looks like it's been playing a lot better than that second table all week."
O'Sullivan had hoped to celebrate his 38th birthday by advancing to the semi-finals of a tournament he has won four times.
But the former world number one fell behind 3-1 to Bingham and he was unable to get out of trouble despite a pair of superb century breaks.
It was a sweet moment for world number 10 Bingham who avenged his defeat to O'Sullivan in the recent Champion of Champions final in Coventry.
