Ambiguity (horse)

Ambiguity was a bay mare with a white face and four white socks[2] bred in England by her owner William Astor, 3rd Viscount Astor. An unusual feature of her appearance, apart from her extensive white markings, was that her left eye was pale blue in colour. The filly was sent into training with Robert John "Jack" Colling at West Ilsley in Berkshire.[3]

She was from the seventh crop of foals sired by Big Game the best British colt of his generation, whose wins included the 2000 Guineas and the Champion Stakes. As a breeding stallion, his other progeny included Combat and the 1000 Guineas winner Queenpot. Ambiguity's dam Amber Flash was a high-class stayer who defeated Chamossaire in the 1945 Jockey Club Cup and was a daughter of Traffic Light, an even better racemare whose wins included the Coronation Stakes and the Park Hill Stakes. Traffic Light's dam Point Duty (foaled 1926) was an influential broodmare whose other descendants have included Mannamead, Sodium, Madelia, Black Caviar and Solow.[4]

In their book, A Century of Champions, based on the Timeform rating system, John Randall and Tony Morris rated Ambiguity an "inferior" winner of the Oaks.[8]

At the end of her racing career, Ambiguity was retired to become a broodmare in England and was later exported to the United States. She produced at least eight foals and four winners between 1957 and 1971:

• Redoubt, a bay colt, foaled in 1957, sired by Court Martial. Winner.[9]
