To me, up until recently, I thought they were the same, until I got to actually thinking about it.
Two point only means two points of contact, and even though I can jump in this position, I also use it for canter work as well, to stay off "my" school horses back and let him move a bit more freely.
So now that I realized that, jumping position is the position I am actually in when I go over a jump.....back flat, hands forward, automatic/crest release, centered over the saddle....letting the horse close my hip angles for me. That being said, I have not jumped a height over 3', so I am not having to put my chest closer to the horses neck like a grand prix jumper might have to.
What is your take on it? What were you taught, and now what do you believe?
**This was placed in english riding so that jumpers, eventers and hunters could comment on it at will, as I didn't want it to be missed in the jumping thread.**
