alright, i’ll try to break it down.
with no super, I would say Chun Li is at a disadvantage to Ken, especially Ken with meter. You basically get a ground based poke match with Ken mixing up dashes, roundhouses, etc.
Ken can punish whiffed fierces and low forwards (if his reactions are good enough), and sweeps work well on her. He can push her into the corner and kill her before she gets meter.
that’s the positive.
On the flip side, if Ken whiffs his rh, or eats 2 or 3 fierces, then Chun’s meter gets filled pretty fast.
Ken is forced to play a ground game against her, he can’t really jump towards a smart Chun because she has toooo many anti air options: air throw, air fierce fierce, back fierce, standing fierce, standing strong, low strong, low roundhouse, standing roundhouse, jab, or kara throw (get the point?).
Once Chun has meter, Ken’s options disappear. Dashing becomes vulnerable to backfiercexsuper or low forward super, fireballs are easily supered through or punished even if it hits or is blocked close enough. RH is punished if whiffed OR blocked.
All his pokes are very vulnerable to getting beaten by Chun’s very good backfierce or low forward. With the threat of low forward super, Chun begins to get throws for free, which kills Ken’s turtle game, and to make it worse, she has an above avg. kara throw.
The standard thought on this matchup is: Ken wins first round by killing Chun before she get’s meter. 2nd round she has one meter, so she charges the 2nd bar for free (ken has no options remember?). Thus, she always has at least one meter, or very close to one meter, and Ken loses the next two rounds.
It’s a very tough matchup for Ken, it is NOT unwinnable, but it is very very tough if the Chun plays smart, safe, and abuses the low forward link.
To put it another way, an average Chun can give a good Ken lots of trouble.
