I have an amazing opportunity...?

What a wonderful opportunity. If you have never ridden a warmblood before you will truly find the experience exhilarating.

If they belonged to me I would not like anyone else to go so far as to attempt to do Piaffe or Passage on them. You should explain to these people what level you have been riding at and if you get to know them well enough maybe ask them for a lesson. But stick to the basics to start with or you won't be asked back! These will be powerful horses, so don't ask for trouble. Good luck.( and look up warmbloods so you can at least make intellegent conversationabout their breeding!)

I probably won't get points for this but I'm assuming that the owners of the horse can do these things, why don't you ask them to show you? I say this because 1. I don't know myself but 2. because if someone can't describe it properly on here, you could end up not getting anywhere, but if you actually watch the precise movements of someone who knows what they're doing, you can see for yourself, and then you will know you are doing it exactly right, AND if they're there when you do it, they can point out if you're doing it wrong.

I don't know about most people, but I think it's way more effective to learn from experience rather than to be told.

You already know the extent to which the cadets at the SRS train before being allowed to ride and to perform the High School movements. Your best bet would be to ask for permission to visit and to =watch= the horses perform under their usual riders. If your hosts think it appropriate they just might let you up on one of them, and might tell you what to do and what NOT to do. Do not assume that knowing a cue is sufficient.
