Altior clinched the jumps trainers' championship for Nicky Henderson with a superb victory in the bet365 Celebration Chase at Sandown.
The crack novice treated last month's Champion Chase hero Sizing Tiara with disdain as he brushed aside the Irish raider, who had set the pace until the second-last fence.
Altior (30-100 favourite) sprinted clear for Nico de Boinville to take his 100 per cent record over fences to six with a ruthless eight-length triumph.
Henderson said: "He's top class. I think we've always known that."
De Boinville said: "He really is a star that shines very brightly. It's an incredible achievement for him and a great day all round.
"He was still a novice coming into open company. He picked up so well. It was just effortless."
Most popular winner of the afternoon was Menorah
He signed off his career in spectacular style by winning the bet365 Oaksey Chase for the fourth year in a row.
The 12-year-old, trained by Philip Hobbs, put in an immaculate display of jumping in the hands of champion jockey Richard Johnson as he put the race to bed a long way out.
Sailing over the obstacles, Menorah (9-4) led over the Railway Fences on the second circuit and soon had his rivals toiling.
Though Traffic Fluide closed the gap on the run to the line, he was still four and a half lengths behind the game and gallant veteran.
Hobbs said: "To win that race four times in a row is amazing.
"That's his last race, he's been retired."
