From my experience, she's covering a lot of good range out of where Chie can touch her. 5A and j.A range is really good. Try to get in her 5A,5B whiff range and swat her with 5C and dash cancel in. Dash canceling 5C is super important in closing the distance and working on fundamental Chie pressure.
Teddie screw is not entirely safe, it depends on where and how it hits. If they end up just about next to you, you can punish.
If you knock him down in the corner, I think 2D,D oki is the best ender off 2AB and it baits his R-Action
How are these people dashing with 5A into more 5A's so fast while moving forward without autocombos?
Why does it seem like some players just jump up, dash, and drop right down with the air turn j.B cross up? Which dashes are they doing?
