All In is a beautiful daughter of the mare Albufeira, who has produced, among others, the gelding Almquist (by Luron), successfully competing in Longines Ranking classes. The same maternal line has also produced many horses successfully competing at 1.30–1.35 m level under junior riders. All In is sired by the rising star of the Nijhof breeding program, the impressive Drummer 2000 Z (Diamant de Semilly × Chin Chin), a brother to horses such as Akarad Hero, King of China Hero and Diamond Touch.
