Bright New Dawn got rolling late to claim top honours in the Three.ie Handicap Chase.
Formerly trained by Dessie and Sandra Hughes before joining Gordon Elliott at the start of this season, the Gigginstown House Stud-owned nine-year-old is seriously talented but also difficult to predict.
As well as winning at Clonmel twice since the turn of the year, he had disappointed at Cheltenham and Aintree and he was a 12-1 chance for his latest appearance.
Jessica Harrington's 100-30 favourite Rock The World looked the likely winner after turning for home, but Bright New Dawn mowed him down after the final fence and got up by a length.
Sizing Codelco was back in third.
"Bryan (Cooper) gave him a brilliant ride - I thought he was very good on him," said Elliott.
"He's been a very frustrating horse. He's either very good or very bad and there has been more bad unfortunately.
"He got a nice pot today and we'll keep him going and see what we can get with him."
Elusive Ivy knuckled down to claim victory in the JLT Handicap Hurdle at Punchestown.
Gavin Cromwell's mare struck gold at the track in far more testing conditions back in January and having run with some credit on her latest appearance at Fairyhouse, she was a 16-1 shot for the opening race on day three of the Festival.
Conditional jockey Brien Kane produced his mount to lead on the run to the final flight and she had just enough left in the tank to hold on by three-quarters of a length from The Brock Inn, with Pakman and Seeyouallincoppers filling out the places.
Cromwell saddles stable star Jer's Girl in the Grade One Tattersalls Ireland Champion Novice Hurdle on Friday.
He said: "The little bit of juice in the ground helped her as I thought the two miles might be a bit sharp. She's stays two and a half.
"Brien gave her a smashing ride and everything went to plan. The last three weeks she has really turned a corner. She got her summer coat and has been working really well.
"She's been Jer's Girl's work companion so hopefully they have brought each other on.
"She'll stay going now and she could go chasing."
There was a thrilling climax to the Murray Spelman Handicap Hurdle, with Nicky Henderson's Cup Final (14-1) gaining a narrow verdict.
Elliott's Jury Duty was a well-backed 5-1 favourite and his supporters must have been counting their money when he went clear from the home turn, but Cup Final finished with a wet sail under Robbie Power and got up by a short head.
Willie Mullins saddled the third, fourth and fifth in Burgas, Tarabiyn and Haymount.
Henderson said: "Obviously with all the hail showers and rain, things have changed dramatically and it's getting tough going out there.
"Robbie said he wasn't travelling from a very early stage. He crept and crept and it was a brave ride to come from there.
"He was just good enough. I was standing with Rich Ricci and a few others. They said 'yes' and I said 'no'. I would have settled for half."
Elliott was back on the scoresheet in the Setanta Sports Mares Novice Hurdle as 6-4 favourite Missy Tata [above] proved much too good for her opponents.
Fourth in the Fred Winter at last month's Cheltenham Festival, the four-year-old received all the allowances in this two-mile contest and eased nine lengths clear of Ria D'Etel in the hands of leading conditional Jack Kennedy.
"She's not a bad mare. She wasn't fit enough at Cheltenham," said Elliott.
"I'm delighted for Jack after getting beat earlier (on Jury Duty). He gave her a grand ride and didn't panic.
"She loves soft ground and could be a mare to go to France. I'll talk to the owners and make plans."
Invitation Only sent favourite-backers home happy with an all-the-way victory in the Kildare Post (C & G) INH Flat Race.
Representing the same owner-trainer combination that claimed the prize 12 months ago with the top-class Yorkhill, the Mullins-trained five-year-old was sent off the heavily-supported 9-10 favourite following an impressive bumper debut at Navan last month.
Patrick Mullins gradually wound up the gallop aboard the Andrea and Graham Wylie-owned gelding and while first Sunni May and then Blast Of Koeman tried to lay down challenges in the straight, Invitation Only saw them off fairly comfortably.
The winning rider said: "He's a big, strong chaser really, by Flemensfirth, and I didn't want it to turn into a sprint. I wanted to control the pace and make it a stamina test.
"I love this horse, he does everything right at home."
A clearly impressed Mullins senior said: "He looks a decent sort. He's a stayer and will go novice hurdling next year.
"Whatever we start off over he'll want two and a half to three miles. We kept him out of the champion bumper for this one.
"He would have been entitled to run in the champion bumper or at Cheltenham, but we kept him back as he came in late. He's a winter horse.
"The pace they went there the horses that were up front finished nowhere. Horses were being burned off in the back straight in a winners' bumper and to me that's phenomenal.
"Patrick's very sweet on him and wanted to go to the front. We had a front-runner in the field in Augustin but he felt he wouldn't be able to go hard enough!"
