Bryan Cooper guided Benefficient home at Prestbury Park
Benefficient rallied gamely to lower the colours of Dynaste in the Jewson Novices' Chase at the Cheltenham Festival.
Tony Martin's seven year old had been mixing it in the top company for much of the season and proved that his victory in the Irish Arkle (where only one other rival completed) was no fluke in this Grade Two contest, registered as the Golden Miller Novices' Chase.
Wearing a hood for the first time, Bryan Cooper gave him a positive ride but the writing looked to be on the wall as Dynaste moved easily to the front approaching two out with Captain Conan in second.
However Cooper threw everything at his mount who responded gamely and Dynaste had no answer having been headed jumping the last.
The well-backed favourite - who was re-routed from the RSA Chase - did pull clear of the weakening Captain Conan who was collared for third by rank outsider Changing Times and Module, who finished fourth.
Ruby Walsh and Marito took a heavy fall at the second last while Willie Mullins' other runner, Aupcharlie, was never able to land a blow.
Cooper said: "It's unbelievable, it's what you dream of as a young boy. Tony said to me that if he gets headed turning in, to just sit on him and let him fiddle away. Some of the others might have had more speed than him but they couldn't get away from me. He winged the last and galloped all the way to the line."
Martin said: "This is what you get up every morning for, to come here with a live chance. I thought if everything went well he couldn't be out of the first three but we were very much afraid of Dynaste.
"We knew he'd get two and a half miles, he got the run of the race and jumped excellent and the jockey was excellent. As far as I'm concerned Ruby Walsh, Barry Geraghty, Paul Carberry and Tony McCoy are out on their own but they are the old guard, this boy is on the way up and he'll be there when they have long gone.
"He's a good moving horse and the better ground helped him. Today was the plan."
Tom Scudamore, rider of Dynaste, said: "He's run a great race and he's the best of the English horses. He jumped fantastically and was beaten by a better horse on the day. It seems that the Irish staying novices are better this year."
A terse David Pipe, trainer of Dynaste, said: "Just not good enough. He might go to Aintree but I'm happy we picked the right race."
