Chun-Li seems like a pretty hard matchup for Guile at first. I remember a local guy was playing with Chun-Li and I remembered when I first played him. He nearly perfected me each time, I didn’t really know what to do against him. Overtime I learned this matchup a little better.
Chun-Li almost has to jump, and she’s such juicy airthrow bait. Don’t become predictable with them, because she has her own airthrow. And some Chun-Li’s with counter air throw you, and win most of the time.
The best strategy against her is to spam out sonic booms as much as you can. You would think they work well against her but they do. Also get use to blocking her overhead flip kick, it’s usually easy to see coming once you’re use to it. Some Chuns with see you courching and go for it, and ex flashkick is the best way to stop it.
This match also has stages. Chun with meter vs. Chun without meter. At the beginning of round one, she’ll obviously be without meter. you can kind of rush her down safely, and there isn’t a lot she can do about it. Smart Chuns will throw out a lot of focus attacks, and dash in and out of ranges. They can be a little problematic, so be careful. Chun has a really really good focus attack.
Chun has a limited rushdown mixup tree, but she does have so really good mixups despite that. I played against one Chun who would get a focus crumple, hit a light attack, which made you flip and land on your feet, then she would do a head stop, into a j.lk, the go from a low light tick throw mixup.
Generally when she doesn’t have meter you can jump in on her safely, damage her (because she takes loads of damage) and then turtle it up.
You also have to be aware of her wakeup. She has a wakeup ex lightning legs, and her dreaded ex spinning bird. Smarter Chuns won’t do a d.RK too often, but be cautious of it, and block accordingly. Also against Chun, you may won’t to practice throw teching, it’s really important in this matchup. There is no one way to escape her mixups besides throw teching sometimes. Throw techs reset the distance.
Overally you want to just harass her with sonic booms when she has meter and get her frustrated. It’s important to get an early life lead and sit on it. I’ve played Chuns who have a similar mentality. You also want to learn how to block in this matchup, Chun can stun you pretty quick.
