Grand Prix Answers
1) Timed First Jump Off. All of the horses that are tied for first place after the first round return for a timed jump off.
2) No faults, as long as the rail or brush box is placed in front of the water jump and not directly over the center. In this case, only a foot in the water or a hoof on the landing lath are counted as 4 faults. Touching the landing lath with the horse's pastern is not a fault.
4) According to the USEF rule book, no.
