get used to it. Chun Li isn’t supposed to jump a lot.
On the ground, Urien’s pokes (standing FP, low RK, and to a lesser degree low MK) are almost on par with Chun Li’s pokes (standing FP, back FP, low MK). It’s when she gets one bar that you need to be careful with your pokes.
One option to deal with Chun Li is to turtle her back. Get bar where you can, try not to eat her low mk -> super. Push her to the corner when you get the opportunity. (crush -> aegis…though watch out again if she has bar). This style of play is really boring, but it might give you a chance against her.
You said that it’s hard to connect Urien’s low fierce. It’s all about experience. I can only suggest you play more matches against Chun Li and try to figure out when are good situations to connect the low fierce.
Oh, and forget about Urien’s SAII. If you say that you’re having trouble connecting a low fierce against her, SAII is USELESS for you.
You used SAII in a tourney…brave man.
