The six-year-old Onassis SB stood out to us for her rideability, willingness and easy scope. She is a half-sister to the auction horse New Valentine SB.
Last year Poker de Mariposa gave a good impression in international 1.40m and 1.45m classes with Kars Bonhof. He is very interestingly bred as son of Nabab de Reve out of the 1.60m Grand Prix mare Ilena de Mariposa (Berlin). Granddam is the top-class showjumping mare Flora de Mariposa (For Pleasure), who has been very successful under Penelope Leprevost (FRA) for years in a row.
Dam Roselinde, a daughter of the influential Zeus, produced excellent offspring, including two 1.60m Grand Prix horses: Upperstar (Jérôme Guery) and Hoselinde (Ella Yunjing Wang), as well as Dodarde E Z (1.45m level with Rhys Williams), Dazard (1.40m with Doron Kuipers) and four 1.30m–1.35m level horses.
Granddam Viola (Orthos) earned the KWPN predicates Keur, Preferent and Prestatie, producing both showjumping and dressage horses. She is also the granddam of the CCI5* eventing horse Urzan.
