Tony McCoy rode his first winner of the Crabbie's Grand National Festival aboard Uxizandre (11/4) in the Pinsent Masons Manifesto Novices' Chase.
The champion jockey was determined to make the most of his partner's stamina and turning for home seemed to have shaken off all bar Western Warhorse.
The Arkle hero was soon beaten off only for Barry Geraghty to conjure a late rally from 7/4 favourite Oscar Whisky who had seemingly blundered his chance away.
Between the last two the market leader looked sure to throw down a meaningful challenge but the Alan King-trained winner was the more fluent at the final fence and went on to score by a length-and-a-half.
The winning trainer said: "He ran a hell of a race at Cheltenham when second in the JLT. We wondered if it was a fluke or not, but clearly not.
"I'm not saying he's ungenuine, but you can disappoint him. He gets the trip well. We had him in the three-mile race on Friday (Mildmay Novices' Chase) and it was a toss-up which way we went with him."
McCoy said: "You could never ride him on a right-handed track, so that limits him a bit. Looking at that, maybe the Ryanair could be a long-term (aim). He's probably improved for his run at Cheltenham."
Frank Berry, racing manager for owner JP McManus, said: "It's good to see him put in another good run after Cheltenham and that'll be it for the year."
Dai Walters, owner of Oscar Whisky, said: "If he had jumped a bit better I think he'd have been closer. Obviously he's going into chasing quite late, but if age doesn't beat him, hopefully he'll keep improving."
Trainer Nicky Henderson said he might look for another race this season.
"It was a great run, Barry was very happy with him and thought he might have got to the winner over the last," he said. "He made a couple of sloppy jumps but finished the race well and it has been a good year for him.
"He didn't really go to Cheltenham, with what happened there, so we might have a look for a race at Sandown. The Celebration Chase would be too short for him but there might be something else - although he won't go to Punchestown."
Western Warhorse, however, has run his last race of the campaign.
Trainer David Pipe said: "He doesn't help himself, but there was nothing left in the home straight. He had a hard race at Cheltenham and hopefully he can go for good two-mile chases next year."
