Jonathan Moore cemented his position as new stable jockey for Rebecca Curtis when steering Irish Cavalier to a surprise success in the bet365 Charlie Hall Chase at Wetherby.
The seven-year-old had too many guns for talented and seasoned campaigners Menorah and odds-on favourite Cue Card to give the Irish rider a notable triumph in his first season in the UK.
Dynaste set the early pace from Virak and Wakanda with Cue Card never too far away.
Paddy Brennan sent Colin Tizzard's star performer into the lead a long way from home in a bid to repeat last year's success, but he could not shake off all his rivals.
Irish Cavalier (16-1) landed in front at the second-last fence and plugged on courageously to lift the Grade Two contest by three-quarters of a length from Menorah, with Cue Card, the 8-11 favourite, only third.
Curtis said: "I thought he'd run well, but I didn't think he'd win.
"He's still only seven and he obviously gets three miles. He's improving every season.
"There were a couple of blips last year, but they were when our horses were wrong - he did win at Punchestown.
"He thrives on his racing, the season before he ran twice at the Punchestown Festival."
Assessing plans, Curtis said: "It's possible he could run in the Betfair (Chase, Haydock on 10 November), we have to start thinking of all the top three-mile races now.
"The more you race him the better he is."
She added: "I'm pleased for Johnny. One thing I promised him when he came was that he'd ride them all, Grade Ones and handicappers."
Tizzard, meanwhile, was not too disheartened by the eclipse of Cue Card.
He said: "He just got tired, that's all. I thought he was going to win, but he tired after the second-last.
"We took him for a racecourse gallop because if we hadn't I didn't want to wish I had done.
"He's only been beaten two lengths, so we'll go to Haydock (Betfair Chase) and see where we are at.
"I'd sooner he won, but I'm delighted with him."
