Star de Mohaison jumps the last clear.

Leading owner Sir Robert Ogden landed his second big-race success in as many days when Star de Mohaison put up a bold-jumping display in an incident-packed renewal of the Royal & SunAlliance Chase at the Cheltenham Festival.

Ogden's famous pink and white silks were carried to victory by Voy Por Ustedes in Tuesday's Arkle Challenge Trophy.

And they were once again to the fore as Barry Geraghty kicked for home four fences out on Star de Mohaison as several of his better fancied rivals fell by the wayside.

The Paul Nicholls-trained five-year-old was being tracked by Back In Front when that rival came to grief two out leaving Idle Talk (33-1) the only serious challenger.

But Star de Mohaison (14-1) was in no mood to get beaten and powered to a six-length win.

Darkness (11-2), who was never jumping or travelling with any fluency, stayed on to finish a further 11 lengths back in third.

Ruby Walsh, who had been on Star de Mohaison earlier in the season, preferred to ride Our Ben this time but the well-fancied Irish raider unseated him at the third fence.

There was a further blow for punters when 9-2 favourite Commercial Flyer was pulled up before the fourth-last after the horse had made a number of mistakes. It was later reported Commercial Flyer had lost a shoe.

Ogden's racing manager Barry Simpson said: "We are absolutely thrilled with that.

"Sir Robert has been coming to this meeting for 20 years, sadly this is the meeting he hasn't come to and we've had two fantastic winners.

"He was in a dreadful storm off the coast of Chile yesterday and I couldn't get through to him at all but we spoke last night and he really was thrilled so I've got some more good news for him tonight. His sea sickness tablets might have worked so he might be feeling a bit better."

Explaining the riding arrangements, Simpson continued: "I think Ruby made his commitment some time ago. Barry rode him at Fontwell and won on him and he obviously wanted to continue with the ride.

"He jumped superb the whole way round and he had everything off the bridle. It was just a case of him standing up and he's flown the last three.

"Aintree is a possibility but like the horse yesterday we'll just see how he takes his race.

"Hopefully he'll be back for the Gold Cup in a year's time but a year is a long time with a racehorse.

"Sir Robert has had plenty of ups and downs so it's nice to be standing here, it's his third Festival winner and we've had two in two days."

Geraghty added: "It went very smoothly all the way. He jumped perfectly and it was easy enough. It takes a lot of jumping round here and he jumped brilliantly.

"Ruby got injured the day before Fontwell and I got the call so it's just as well I went.

"He's only a five-year-old and has got a bright future. He was getting 8lb and there were a lot of fallers but still he's done it well."

Tom George, trainer of Idle Talk, said: "I wish the race had been yesterday as the ground might have been a bit slower.

"He has run a great race but there are no immediate plans. He shows you everything you want in a National Hunt horse and he could be a National type in the future."

Charles Egerton, responsible for Darkness, said: "He's an excellent horse and has run a blinder.

"He might have only finished third but you need to look at where he came from to finish third and that shows his talent.

"He didn't travel very well which didn't help him. If he hits a flat spot it's in his head.

"We'll see how he is but he might go to Aintree."

Back In Front's trainer Edward O'Grady had high hopes of his runner until the mishap occurred.

He said: "It was sad he fell because he was going well at the time. But he is OK."
