Day Seven LIVE
21.35 - Trump 'had to up game'
"You've got to play [your best] against Ronnie otherwise you lose," Trump said.
Every time I play him I know I've got to up my game to stand any chance.
"It's a tournament I enjoy coming back to and the fans in Belfast and Northern Ireland are amazing.
"It's been a good start to the season and some more finals with Ronnie will be nice - I learn something every time I play him.
Judd Trump: I don’t know what happened out there
21.25 - Ronnie hails 'fantastic' Judd
"It was open, free-flowing [and] quite quick as well which is nice," O'Sullivan said. "Everyone must have enjoyed watching that.
"I was enjoying watching Judd play some fantastic shots, some great break-building.
"I've loved [the tournament], it's a brilliant series, everyone's enjoying it."
21:20 - Trump seals it
What a final. Trump seals a 14th ranking title of his career. The Bristolian needs only one visit to seal the win, defending his title with an 84 in frame 16 to beat the five-time world champion 9-7.
21.01 - Trump 8-7 O'Sullivan - better and better...
You keep thinking this cannot get better and it does. O'Sullivan with a sensational 135-break, he neglects to go for a tricky black for a total clearance.
135 break from O’Sullivan holds only delays the inevitable
20:45 - This is snooker of the highest calibre
Judd Trump takes frame 14 with a 126, his fourth ton of the final. The world champion is one frame away from defending his Northern Ireland Open title.
20:25 - O'Sullivan steals frame 13 to close to within one frame
That was a crucial, crucial steal from the Rocket, who, behind some tremendous shot-making comes to the table 55 in deficit before sealing the frame with a break of 76.
20.00 - Trump 7-5 O'Sullivan
What a way to respond! O'Sullivan notches nine red and blacks to put himself on course for a 147 before missing a long red.
19.49 - So near to a maximum! Trump 7-4 O'Sullivan
15 perfect reds from Trump but he left himself a tricky long cut for the 15th black and missed it on the fat side - cue sighs all around. What an exhibition this has been though.
15 reds, 14 blacks, 1 kick, no maximum – Trump gets agonisingly close to a 147
19.36 - Trump 6-4 O'Sullivan
A superb, quick-fire 106-break from Trump and the lead is back to two frames. It might not last long but no one in Belfast will be asking for their money back.
19.20 - Trump 5-4 O'Sullivan
Ronnie is back within touching distance after winning the first frame of the evening session.
19.00 - We're underway.
18.50 - Here we go...
The players are ready to take to the baize for the second session, let's hope it will live up to the sensational first eight frames.
15:20 - Trump 5-3 O'Sullivan
We said he needed this fame, and Ronnie delivered. He makes a speedy 86 to move within two frames of Trump once again, but the champion is certainly in the ascendancy.
These two will be back in a couple of hours to play down to a result with the victor claiming the Alex Higgins Trophy.
They will be live on Eurosport and on the Eurosport Player from 7pm, or you can follow the action right here as well.
15:05 - Trump 5-2 O'Sullivan
Now we have a significant gap opening up and Trump is really motoring. That probably would have been a maximum too, had it not been for a monstrous kick on the 12th red. That is brutal, but it is still 88 and the frame to Trump. One frame left this afternoon and you feel O'Sullivan badly needs it.
14:50 - Trump 4-2 O'Sullivan
Two bites at the cherry required for Trump this time but O'Sullivan misses his opportunity by a distance and the two half-century breaks are enough for Trump to restore his two-frame lead.
14:35 - Trump 3-2 O'Sullivan
This is turning into a real doozy. Trump misses a long red and O'Sullivan punishes him with a break of 89 to cut the deficit in half once again.
Remember they play eight frames this afternoon before a maximum nine tonight. You wouldn't bet against them needing all 17 at this rate.
Trump error allows Ronnie in for masterful 126 break
14:05 - Trump 3-1 O'Sullivan
The two-frame gap is restored and once again Trump keeps Ronnie cold, capitalising on a loose break-off to make 123, only missing the final black.
An impressive first mini-session from the defending champion.
'This shows just how good Trump has been!' | Amazing break against Ronnie
13:55 - Trump 2-1 O'Sullivan
Questions answered. Well, one at least. Ronnie is on the board in trademark fashion, making the frame safe in just over five minutes before racking up a clearance of 126 and there is a mighty cheer from this Northern Ireland Open final crowd.
13:45 - Trump 2-0 O'Sullivan
Trump is by far the most fluent of the two superstars so far and in two significant visits to the table he secures the second frame. Ronnie has questions to answer already.
13:25 - Trump 1-0 O'Sullivan
A really high-quality safety battle ends with Trump hammering a red into the corner pocket and putting together a fluent break of 68 to take the first frame, much to the delight of the crowd.
No shortage of that signature cue-ball control from Trump either, coming off cushions at speed left, right and centre.
12:45 - Are you ready?
It's time for the final we were all hoping we might see as Judd Trump and Ronnie O'Sullivan face off once again.
It's a best-of-17 affair split over two sessions today, with the first kicking off at 1pm.
And remember you can watch all the action live on Eurosport or you can follow the latest right here.
Oh, and just in case you somehow missed this yesterday...
The greatest shot of all time? | Trump's moment of magic
Day Six action
O'Sullivan to face Trump in a repeat of the 2018 final.
If O'Sullivan wins the 2019 Northern Ireland Open, the 43-year-old will move ahead of Stephen Hendry on the all-time ranking title winners list.
However, the five-time world champion is not too fussed by that particular record.
"I am sorry to disappoint you but, you know, when you have been doing it for so long you find other things that motivate you,” said O’Sullivan.
"For me, it was never about records and stuff like that. It was just about trying to enjoy the game. If you can enjoy the game, you have more chance of longevity, you know?"
20:45 - O'Sullivan sets up a Trump showdown
It takes multiple trips to the table but O'Sullivan gets it done, beating Perry 6-1.
20:30 - The gentleman Joe Perry gets on the board
Perry prevents the ignominy of a whitewash as he takes frame six to surely just extend the inevitable.
20:15 - A whitewash on the cards?
This is vintage O'Sullivan, who now adds a 90 to open a 5-0 lead.
19:50 - The Rocket is flying at 4-0 ahead of the mini-interval
O'Sullivan is looking to get business done early and quickly, he adds another two half-centuries - 54 and 72 - to his 58 in frame one to move to within two frames of the final.
19:20 - O'Sullivan takes two-frame lead against Joe Perry
O'Sullivan takes the first frame courtesy of a 58 and backs that up in a tactical second top open a two-frame advantage. The Rocket was the beneficiary of a sizable portion of luck in frame two when he fluked the yellow while attempting to escape a snooker.
‘Fluke of the decade!’ – O’Sullivan gets the rub of the green against Perry
18:45 - We are back
The talk of the snooker world remains Judd Trump's incredible shot...but there is a semi-final in the offing between Ronnie O'Sullivan and Joe Perry.
16:25 - Trump WINS!
And another! Trump finds form finally, clearing the table for 136 and the match. It was not a thriller in truth but at least Trump reminded us of all his quality eventually.
He will face either Ronnie O'Sullivan or Joe Perry in the final - we'll be here to take you through the action from 7pm tonight. See you there!
16:10 - Higgins 3-5 Trump
At last a decent break! Still no century, but Judd Trump has broken 50 for the first time and is one frame away the chance to defend his title on Sunday.
15:40 - Higgins 3-4 Trump
Higgins loses a safety battle with two reds remaining and Trump promptly takes advantage to move within two of the final.
15:10 - Higgins 3-3 Trump
No-one can take hold of this match. Both men trade breaks and then Higgins tries to double the last remaining red, leaving Trump the chance to clean up. If either of these men hit some sort of form, you'd think a place in the final is theirs.
14:45 - Higgins 3-2 Trump
We are still waiting for this match to catch alight to be honest as Higgins scraps his way to a lead for the first time since the opening frame - but he has followed it by immediately giving Trump the chance to get among the balls in the sixth.
14:15 - Higgins 2-2 Trump
At last, some snooker breaks out! Higgins makes 78 to make sure they go into the interval level after four frames. Trump by the way is yet to pass 42...
14:00 - Higgins 1-2 Trump
After a strong start, it's all going wrong for John Higgins, who sees Trump scrap his way to the third frame of the day. It's a new cloth on the table today and the suggestion is both players could be struggling to adapt. My suggestion would be that Trump has just started to pick it up, ominously...
13:45 - Higgins 1-1 Trump
I'm not quite sure how John Higgins hasn't won that frame. He had three separate chances to clean up but each time made a mistake. Trump similarly spurned the first two but finally gets over the line - having played his worst snooker of the tournament so far, according to Eurosport commentator Joe Johnson.
13:15 - Higgins 1-0 Trump
The Wizard of Wishaw is among the balls straight away after a poor break from Trump and while it takes him two goes, Higgins has the frame and draws first blood in this best-of-11 encounter.
13:00 - Here we go...
Right, the players are being introduced so we are seconds away from getting underway on "Semi-final Saturday" and what a set of matches we have in store. First up, it's Trump v Higgins.
Day Five action
22:28 - That's all, folks!

19:20 - The Rocket leads
Murphy was in charge of this set but O'Sullivan needed just one visit to the table to overturn a 42-point deficit and he's 1-0 up after a break of 77.
19:04 - O'Sullivan vs Murphy
A huge match this. And we're shortly underway. Perry vs Ursenbacher also kicking off in Belfast.
18:22 - Higgins wins it
A rogue red costs Selby and Higgins cleans up to make the semi-final. Selby's hopes of a Home Nations sweep are over.
18:00 - Selby levels
An absolute thriller on our hands here. Selby levels at 4-4 and takes us into a decider.
17:40 - Selby one behind
The Jester is grinding his way back into this one and now he's just 4-3 down. Can Selby force a decider or will Higgins finish him off?
17:24 - Selby pulls one back
Hold on. A hope? A chance? Selby brings it back to 4-2 and he's ahead in the seventh frame.
17:04 - Higgins on the verge
He's 4-1 up after another fine frame. Selby has given an uncharacteristically error-strewn performance.
16:28 - Higgins goes two up
It's 3-1 to Higgins and the Scot needs just two more frames to deny Selby a chance of the Home Nations sweep
16:15 - Higgins 2-1 up
Higgins is still in front but the two titans are locked in a battle of snookers in a tight fourth frame.
15:00 - Higgins strikes first
Higgins punishes a fairly presentable missed black from Selby and the Scot capitalises to open up a one-frame lead.
14:45 - Next up: Higgins v Selby
14:30 - Done and dusted - Trump through...
Trump dispatches a tidy red to set up a break of 105 and move into the semi-final to face either John Higgins or Mark Selby. Trump was in irrepressible form as predicted by Jimmy White.
14:00 - A quick-fire double from Trump puts the Bristolian one frame away
A 66 and a 73 from the 30-year-old see Trimp move to within one frame of a semi-final encounter with either John Higgins or Mark Selby.

Its takes multiple trips to the table but Hamilton is on the board, cutting the arrears to 2-1 with one frame to play ahead of the interval.
12:50 - World number one takes two-frame lead
Defending Northern Ireland Open champion Judd Trump backs up a 106 in frame one by squeezing through the second frame - following some loose safety play from the Sheriff of Pottingham - to put himself within three frames of a semi-final appearance.

A loose break off from Robertson allows Joyce in, who moves to a 3-2 advantage courtesy of the 100th century of his career - a total clearance of 137.
22:45 - Sluggish Robertson draws level
Robertson was on for a 145 break but a jawed black allows Joyce back in requiring one snooker. However, despite getting back in Joyce can only make a 40 and the The Melbourne Machine gets it over the line.

20:53 - Ronnie goes through
It was a shaky start, but O'Sullivan is through after winning the sixth frame 69-8.
20:48 - Big miss for Lines
O'Sullivan goes 22-0 up but he misses a blue in his attempt to hit the pack of reds. That brings Lines back to the table, but a red agonisingly stays out of the middle pocket and O'Sullivan is now putting more points on the board...
20:43 - Ronnie leads 3-2
O'Sullivan has certainly improved in the last two frames, but it hasn't been easy. He can't quite close out the fifth frame at the first time of asking, but after Lines squanders a half-chance, it's O'Sullivan who moves 3-2 up.
Lines shakes his head as they head off for a break. Not surprising. He's had chances.
20:20 - Ronnie levels up at 2-2
O'Sullivan misses his opening attempt at a red and that allows Lines to build a 45-0 lead, but a miss on a risky red allows O'Sullivan back to the table, and with a generous spread of reds, he knocks in 87 to tie it up.
We're in a best-of-three showdown now...
20:18 - Lines 2-1 up against O’Sullivan
This is far from plain-sailing for the five-time world champion, and O’Sullivan is now down 2-1 after losing a tight third frame.
He looked as though he was about to edge it, but the white ball caught the middle pocket after he potted the white, leaving him just one point up with just the black to pot.
And after missing a black along the cushion, it was Lines who had a simple pot into the middle to win it 60-54.
Remember– it’s best-of-seven snooker, meaning Lines is two frames from victory.
19.55 - Lines levels up
There's 51 left on the table and Lines is 61 up, but O'Sullivan gives a wee nod in his seat to signal he won't be coming back to force some snookers. It's 1-1 now after O'Sullivan took the opener 58-44.
19:00 - Action under way
The evening's action in Belfast has begun. Neil Robertson vs Mark Joyce still to come later.
18:50 - 'Ronnie is beatable'
"It depends which Ronnie turns up, sometimes I get the impression that he doesn’t want to be there and he can’t really be bothered," Lines told Metro.co.uk.
"But when the real Ronnie turns up he’s virtually unplayable, I’m hoping that one doesn’t turn up. Having said that, I’m not too sure, because for the opponent that’s quite off-putting, it can work the other way psychologically when you know your opponent isn’t trying and he’s playing questionable shots.
"I feel it can get under your skin a little bit, I hope he turns up and he tries because it’ll be easier for me, I think. When you know he’s not trying, in front of the cameras, it could get a bit daunting.
He’s beatable, everybody’s beatable, if I play my best and he plays slightly below his best then hopefully I can give him a decent game.
18:45 - Ronnie O'Clock
We're live on Eurosport 1 and the Eurosport Player as Ronnie O'Sullivan begins his quest for a first Northern Ireland Open title against Oliver Lines.
You can also catch Kyren Wilson vs Alan McManus on the Eurosport Player.
17:25 - Allen through, White out
A gutsy performance from home favourite Mark Allen, whose 4-1 victory over Sam Craigie is somewhat flattering after a close encounter.
Meanwhile, Eurosport's very own Jimmy White is out after he fell 4-2 to Peter Ebdon.
16:46 - WATCH: Bingham's 147
Stuart Bingham makes 147 maximum at Northern Ireland Open
16:45 - Allen pinches frame, leads 2-1
He was trailing in the third frame, but a fluke after being snookered helped Allen steal it despite Craigie's 71. Tough blow for the world No 62.
16:25 - Ebdon-White locked at 2-2
This could have been a professional match-up in 1991, and here we are in 2019 reporting that it's 2-2 between Peter Ebdon and Jimmy White.
White has just take the fourth frame after Ebdon bounced back to lead 2-1.
Meanwhile, Allen is tying 1-1 with Craigie but looks set to lose the third frame.
16:05 - 147 steers Bingham to win
Stuart Bingham knocked in the sixth 147 of his career en route to a 4-3 victory over Lu Ning earlier today.
The maximum came in the first frame and inspired Bingham into taking a 3-0 lead, but Lu Ning responded with the next three frames to force a decider.
However, it was Bingham who prevailed 63-45 to reach the second round.
15:45 - The boys are back in town
We've got a blast from the past here: Jimmy White taking on Peter Ebdon, where it is a frame each. It would be pretty massive if White were to beat Ebdon - but even if he doesn't, he'll be here all week as a pundit on Eurosport's live coverage of the action.
Mark Allen is in action this afternoon too and he dropped the first frame of his home tournament to Sam Craigie and is fighting for the second.
15:00 - Trump sees off spirited Cahill
We have our first major result of the day and it is not a surprising one as Judd Trump is through - but not without a fight.
The world No 1 started with three centuries - breaks of 106, 122 and 111 - to take the first three frames in quick time.
Cahill fought back to make it 3-3 though - only for a relaxed Trump, fresh from a Champion of Champions final defeat to Neil Robertson, to triumph with a break of 75 in the final frame.
Day One round-up - Ding stunned as Lilley secures first-ever pro win
22:12 - Shaun Murphy 4-0 Fraser Patrick - Whitewash
A difficult evening for Patrick, but a perfect one for Murphy, who takes the next two frames with breaks of 95 and 76 to reach the second round in style.
21:50 - Shaun Murphy 2-0 Fraser Patrick - Murphy motors ahead
A solid start from Murphy as an 80 helps him take the opening frame. A 65 is then not enough for Patrick in the second as Murphy takes it 78-65.
What If...? | Shaun Murphy
