Dynaste, trained by David Pipe, powered up the Cheltenham hill to win the Ryanair Chase under jockey Tom Scudamore
The grey, brought with a perfectly timed challenge by Scudamore, flew from the final fence for an emphatic success.
Beaten into second at the Festival last year, he went one better in tremendous style.
The front-running Hidden Cyclone kept on for second while Rajdhani Express posted a career-best effort in finishing third.
Benefficient travelled well for a long way, but his run petered out and he was pulled up before the final fence.
Kauto Stone set the early pace with Scudamore content to sit in the pack and adopt waiting tactics while Hidden Cyclone was also prominent, settled on the heels of Benefficient in third.
Andrew McNamara was first to kick, assuming the lead three fences from home with Rajdhani Express following him through.
That pair were still in control coming down to the last but Dynaste was really starting to motor and he jumped the final fence in great style before accelerating away to win by two and a quarter lengths.
Rajdhani Express was the same distance back in third.
Al Ferof stayed on at the one pace at the finish.
