I’m not sure if people already know this or not so don’t bite my head off if it’s not new to you. I used to think this move really sucked (EX hcb+K). However, I never really played Chun Li that much and never really got deep into her playing strategy and tactics.
I’ve just started to look into her options and I’ve found out that the EX hcb+K is invincible in the first few frames of the move. It is invincible to all normal and special moves from what I can tell but is only invincible to certain supers. Take for instance a hadoken, she can easily go through it with this move but if you try to go through a shinkuu hadoken she’ll get waxed. It can avoid super throws including the Stungun Headbutt super. It’s not good for anti-air b/c it’s too slow. You can’t use it against dragon punches b/c the dragon punch has to many active hit frames. It’s weird b/c it will go through stuff like Yang’s super art I but not other supers. It’s not a move that you’ll be using all the time but it can come in handy sometimes though like against Q’s dash punches and such. You cannot tech roll this move if it hits and is totally safe when blocked but it is slow to hit which makes reaction parries very dangerous.
If you play the arcade version and you’re hounded by unblockable Urien aegis reflector you can use this as you get up off the ground when standing up into the reflector. What it will do is make you get hit with the reflector in the air which can mess up the opponent’s combo and possibly reduce the damage given. If you’re gonna take damage you might as well take the least amount possible right? You must time the move to be a perfect reversal off the ground though to work.
Some other things I’ve found out about Chun Li is that you can super jump cancel from her close standing hard kick. This means that you can cancel a super from it by doing c.FK–>qcf,qcf,uf+P or K for the super. The c.FK is also good for dizzy juggles and reset Kikosho juggles. Against a STANDING Hugo you can do a c.FK that hits then super jump cancel forward into a d+MK and if Hugo attempts to duck block he will get hit which means he is forced to block it high. You can then jump off the wall if you’re close enough to it. It’s cool to watch a good Chun Li jump off the wall alot and be crazy all over the place. Wouldn’t you agree?
