Cape Tribulation struck for North Yorkshire trainer Malcolm Jefferson in a driving finish for the Pertemps Final at the Cheltenham Festival.
Denis O'Regan got a great tune out of the 14-1 shot to join Cantlow at the final flight and then gallop on strongly up the hill to land a cosy success.
Catch Me stayed on resolutely to take second, three-quarters of a length behind the winner.
Cantlow was another length and a quarter away in third, with Houblon Des Obeaux fourth and Reindeer Dippin fifth.
Winning owner David Abell said: "It's amazing for a small trainer to have a winner here, usually the big trainers clean up.
"He won a Grade Two by 20 lengths but it's been downhill ever since.
"We put him back over hurdles and it seems to have worked.
"Malcolm always said he was really good."
An emotional Jefferson was understandably thrilled.
He said: "He was pipped on the line in two decent novice chases and this year things just didn't go right for him over fences.
"We worked him over hurdles at home and you could see that he enjoyed that more.
"He is quite a talented horse and he's given him a brilliant ride.
"It's been a long time since my last winner here."
Trainer Edward O'Grady felt runner-up Catch Me had turned in a career-best display at Cheltenham.
He said: "I'm very pleased with him and he stayed on all the way to the line.
"It's nice to see him run so well and that is probably the best he's run around Cheltenham."
Trainer Paul Webber said of the third-placed Cantlow: "The ground is riding a little bit slower, which
hasn't helped him and it's blunted his speed.
"From our point of view they probably over-watered, but he's still run a good race and he'll probably go to Aintree now where he'll get his ground."
