One comment on the previous rider of the 1 on the other horse. You are right, we do not know the circumstances for the mount but I can't tell you how many times a rider took off mine and rode the other horse and I beat him. Happens a lot. It always makes you feel a little better when you play into the rider move and a little leery if you are against that move but once the gates open, it doesn't really matter.
