Every normal in the game can be beat by any other one in the correct situation. Irrelevant point, so to speak.
That’s not how you define a matchup and choose your strategy. Zangief would destroy Sagat with this kind of tech, you know, Zangief just have to SPD that far HK…
Let’s see how I see the match up.
Bad points :
She walk fast forward and backward, her backdash is godlike, she have pokes that reach WAY fewer than you, she can poke you where you think you’re safe (f.mp). And she’ll do it ! Chun doesn’t want to get close, but you do ! You have to take risks (initiatives at least), not her. She’ll do this with no effort while at the same time you’ll need a lot of concentration to read and time (or most likely gamble) your normals to beat hers. If you beat 1/3 of her pokes, witch is already a great result, you’ll die first. When she get super/ultra you better stop whiffing shit anywhere on screen. Her anti air are good, it’s not a good idea to test it just because you have no idea what to do. If she’s in control of the ground, of course she’s baiting you to jump ! Finaly, you have no life to spare on tries and errors, you have no life to give away just to prove your point against one of her poke.
Good points :
Slow ass jump make her air threat unlikely a concern unless you whiff a sweep, whiffing things doesn’t give her a free jump in. You can focus more on ground game because sudden jump is easy to punish late. Her only solution is her Hazanshu, but once you train against that move enough, you’ll block it right, and even find the punish that will put you ahead in health. Slow jump also make your fireball zoning more efficient in this matchup.
Once knocked down she’s easy to safe jump and OS. She’s tatsu sweep-able and weak to vortex. jump HK+OS > DF kick on her obviously.
With all this in mind, you build your own plan, with player habits, round reads, patience, safety, respect.
Like against Guile, stay safe, win the fireball game straight, and you’ll turn the game more towards the "good points"
In round 2 if she have super, good luck with zoning. but you’re fast, you have air fireballs, DF palm whiff/bait, mobility, and the datas of round 1.
