Irish jockey Barry Geraghty benefited from Tony McCoy's choice to ride At Fishers Cross as he guided More Of That to victory in the Ladbrokes World Hurdle.
The 15/2 chance battled with heavy favourite Annie Power, before pulling clear as they approached the line - winning by over a length.
Questions were raised as many believed the Jonjo O'Neill charge wouldn't stay the trip. He proved many wrong as he flew up the hill defeating Ruby Walsh - who was on the 11/8 favourite.
Big Buck's, who was aiming for a record fifth win in the race, was beaten a way out and never got into his stride under Sam Twiston-Davies.
The 11-year-old never looked like challenging and finished fifth. Paul Nicholls, trainer of Big Buck's said after the race that his charge will be retired after a glittering career.
AP McCoy and At Fishers Cross had every chance, but approaching the last McCoy's horse failed to live with the leaders and finished the race with a creditable performance in third ahead of Zarkander.
