Kind of thinking this also.
I have 2 horses that I think would fall into the category of needing a confident rider:
One is a stubborn WB that gets along well with my husband because this horse requires strength, and someone more stubborn than him :lol: He is also a big mover/not easy to sit. If you are not confident in what you are asking he will escalate. If a confident rider is on him he packs around quite nice. If you are not confident, next think you know he’s spooking, stopping, kicking out at indecisive aids, and may pop his front end off the ground (very small rear) because he knows he can intimidate certain riders and get away with it. To me, he’s not a bad horse, but he’s an active horse. You cannot be insecure or a passenger on him. Pros that have ridden this horse have liked him very much.
The other is a PRE that is very sensitive. He is sensible but requires a rider with body awareness. He’s also quite looky so you need to be able to have a sense of humor because he spooks at his own shadow or droppings (yes, his vision is fine). I don’t know if he gets bored, isn’t sure, or is a joker sometimes. He can make quick movements and is a thinker. I think a less confident rider may be ok, but I also think he’d take advantage with the spooking thing…which could scare off less confident ammy in some cases. Oddly enough, he’s my favorite horse.
So those are my 2 examples, and what I might think of when a horse needs a confident rider. Or the horse may still be insecure in its training and just need more miles from someone that is confident and skilled.
Of course this is horse sales so the horse could very well be a rearer that can also buck his rider to the moon out of no where. It’s just such a broad phrase. I think most buyers would shy away due that statement, it could mean so much.
