Diamondsandrubies in Cheshire Oaks mix Aidan O'Brien's Diamondsandrubies is among a field of 12 for the Arkle Finance LTD Cheshire Oaks at Chester on Wednesday. The Fastnet Rock filly is out of Quarter Moon, who won a Moyglare as well as finishing second in the Irish 1000 Guineas and both the English and Irish Oaks. A winner at Tipperary first time out this season, she was third in what looked a strong Listed race won by Bocca Baciata at Navan. Andrew Balding's Victoria Pollard won nicely at Newbury on her racecourse debut recently and steps up in class. The Sir Percy filly hails from the family of useful stayer Victoria Montoya. Daniel Kubler runs the unbeaten Affileo, who is two from two on the all-weather, while Clive Cox reintroduces Loaves And Fishes, a good winner at Haydock on her only outing last season. Michael Bell runs Banzari, a 10-length winner at Nottingham last term while John Gosden is represented by Zamoura and Entertainment. Jasmine Blue, Mile High, Sweet Dream, Tepeleni and What Say You complete the field. Later on the card O'Brien runs the interesting Sir Isaac Newton in the Homeserve Maiden Stakes over an extended mile and a quarter. The Galileo colt cost 3.6 million guineas and is a brother to Oaks runner up Secret Gesture. He had one run at two, when second to Dermot Weld's Zawraq.
