She basically has 3 high Ks to look out for, though you'll rarely see one of them:

7K (the NH liftstun / CH launch) that turns her BT is a high kick.
9K is also a high K (similar animation, but no forced BT transition). This one is far less common than 7K.
KK is that two-hit string that causes the sitdown, and the first hit is a high (second is mid).

yeah i asked because i got the closest with her. also even in lag ive realized i can hold her roll kick on reaction. they try that shit on me again im they'll taste hi advance counter

Are you talking about her 3H+K or her 3P+KK?
3H+K is the rolling kick, whereas 3P+KK is the multi-hit kick that leaves her BT.
