Djakadam was out of luck in a dramatic renewal of the Grand Steeple-Chase de Paris at Auteuil.
Willie Mullins’ raider made little impact on the Grade One over three and three-quarter miles, as the Guillaume Macaire-trained On The Go snatched victory on the line in the hands of James Reveley, who was winning the race for the third year in succession.
There was chaos at the first fence, where the Macaire-trained So French, victorious for the last two years, was one of three casualties. So French was brought down, as was Roi Image after Bipolaire fell.
Djakadam managed to avoid the trouble and David Mullins had the nine-year-old well positioned at one point until he started to lose ground on the final circuit.
Milord Thomas, successful in 2015, made an early bid for glory, but he was hauled in by Perfect Impulse, who looked set for victory.
However, Reveley had other ideas and galvanised On The Go (9-1) to join issue in the straight.
The pair fought out a terrific finish, with On The Go getting up in the final strides to give Macaire his fifth triumph.
Macaire also saddled the third horse, Edward Argent.
Bapaume fared best of the Mullins runners when second behind runaway winner De Bon Coeur in the Grande Course de Haies d’Auteuil.
Stablemate Yorkhill led for a long way, but had nothing left to give when headed by De Bon Coeur after jumping the third-last flight.
The 9-4 favourite, trained by Francois Nicolle and ridden by Thomas Gueguen, was taken to the near-side rail and drew well clear.
Bapaume just got the runner-up spot ahead of Dalia Grandchamp in the Grade One hurdle race.
L’Ami Serge, who took the prize 12 months ago for Nicky Henderson, could never get into a challenging position, while the Nick Williams-trained Tea For Two could never get competitive for Lizzie Kelly.
