Nina booked to ride Organised at Aintree Arthur Moore confirmed today that his niece Nina Carberry will ride last year's Irish Grand National winner Organisedconfusion in the Aintree Grand National on April 14th. The Naas handler said: "Organisedconfusion is due to run at Leopardstown next weekend and we will take it from there. He was a little sore after his fall at Leopardstown the last day, but he is fine now." On last year's Irish Grand National success, he said: "It wasn't a surprise, we were very happy with him going into the race and everything went well during the race. He had run in the Leopardstown Chase last year and he was a good staying-on third in that so we felt he was entitled to take his chance in the Irish National. "This year the Irish National and the John Smith's Grand National are the same week, and it will all depend on how things go at Leopardstown next weekend before deciding where we go." The last seven-year-old to triumph in the John Smith's Grand National was Bogskar in 1940, but Moore believes the demands of Aintree will pose no problem to Organisedconfusion, currently a 33/1 chance with Betfred, the official betting partner of the John Smith's Grand National meeting. Moore continued: "He was mature enough to win the Irish Grand National at the age of six, so I don’t see why his age would be a problem. He has plenty of experience and the ground wouldn't be a worry either - he has won on good and he has won on heavy. "I am very happy with 10st 8lb, it is a lovely racing weight and, all being well, Nina Carberry will ride him." Organisedconfusion fell at the first in the Leopardstown Handicap Chase on January 28th when partnered by Carberry whose only other ride on the horse was for his Irish Grand National victory. Carberry will be bidding to become the first amateur to win the John Smith's Grand National since Marcus Armytage scored on Mr Frisk in 1990.
