JL..Silviniaco Conti is unlikely to go for the King George as Nicholls has already stated he won't be as effective going right-handed !
I seem to remember him winning a hurdle race at Ascot in very impressive style a couple of years ago, but as you say Nicholls knows the horse better than I. Then again, PN always said Kauto Star was always better over a left handed track did he not?
