Well, you’ve got a very unusually bred horse in Amacook. Top side has Wild Risk in the 3rd, which is extremely rare. Wild Risk is one of the truly great TB lines in sport throughout the Western World. Monarchy was a full sister of Round Table, and those lines are famed for long term soundness.
The bottom is much more unusual, but has something that almost makes my heart stop. You’ve got linebreeding to Wise Counsellor, the last of the Great American Herod/Hanover line sires. The mare, Stepwisely, was the also dam of Bolero, and has multiple horses in Dr. Birdsall to her credit.
Stefan the Great is Dollar line from The Tetrarch/Roi Herode, and was the sire of Silver Beauty, dam of Spotted Beauty. This is a wonderful sport horse line of mares that has made it’s way into SF Breeding through Dark Tiger. Stefan The Great is also the damsire of Great War, who was a very famous GP jumper and the sire of Miss Budweiser and damsire of New Twist.
Chance Play is a son of Fair Play and is in the pedigrees of A Fine Romance and Kluwall. Tintagel has three in Dr. Birdsall, and Bull Lea and Sir Gallahad both have inches of descendants who were champions in the jumping pursuits. Watch Your Step has one. Darter is listed in the pedigree of Chance Step, AHSA Champion Junior Hunter in 1968 and 1969, whose sire was Quiet Step.
If the other side is anywhere near as good as Amacook’s, you’ve found a treasure in far more ways than one.[/QUOTE]
Wow! I think that vineyridge is the treasure, here 
It sounds like this mare is worth breeding, just based on the above post!
