The repeat of last season's UK Championship final lived up to expectations as Trump won a battle full off fluent scoring to earn a meeting with Peter Ebdon on Friday. The World No 2 hasn't won a ranking title since his victory in York last December but is now just two matches away from the £125,000 top prize.
Allen won the first frame with a break of 83 before Trump levelled with a 70 and added the third. A run of 98 from Ulsterman Allen made it 2-2, but he had to spend some time in his chair after the interval as Trump rattled in 75 and 107 to go 4-2 ahead. Allen pulled one back with a 121 then Trump responded with a 65 to lead 5-3.
A run of 104 from Allen closed the gap and he came from 41-0 down in the next to make it 5-5. Trump got the first chance in the decider and made 60 before failing to land on a red when splitting the pack. Allen still had hope at 61 points down with five reds left, but after Trump played a brilliant snooker behind the black, Allen left a red to a centre pocket and his opponent potted it to seal victory.
"It was a good game, we both played well," said Bristol's 23-year-old Trump. "I had a good lead then I was just trying to finish it off. I kept going into the pack and landing on nothing so I was getting frustrated. But I just had to try to stay patient and wait for a chance.
"It will be a different challenge against Peter tomorrow. I'll just have to play my own game, try to get in front and try to dominate the match."
Ebdon had a far more comfortable victory, although his 6-0 win over Ricky Walden took 50 minutes longer than Trump's match.
A top break of 81 helped China Open champion Ebdon stay on course for his second ranking title in China in 2012.
"It was a scrappy match, one for the coinesseur," admitted Ebdon. "But I'm really looking forward to the semi-final against Judd and playing a best-of-17 match in our joint-second most important ranking event. Every match is different so you have to play it as it comes."
