With Casall and Corofino II in his pedigree, Cheecker has an interesting background. His grandam Helena V jumped at 1.40m level, as did her product Cochise (Corofino II). Great-grandam Wienna I produced a 1.30m and a 1.40m level show jumping horse. Show jumping genes have been anchored here for generations.
