scl = Standing close.
c.lk, s.lp, s.cl.hp actually works against a few characters… Abel and Seth I know for sure, probably more… but ONLY after a high frontal jump-in attack. (A high jump attacks actually leaves you closer than just walking up and attacking). This is really great against those Abel/Seth because you get to cancel into EX CW. hehe.
As for the c.lk, s.lp, c.lp into rekkas combo, and the standing jab whiffing… Here are some lists:
Standing jab will whiff against crouching (not in block)
Cammy
Chun Li
Honda
Guile
Vega
Gen
Everyone else gets hit by the standing jab if they’re just crouching there.
If they’re blocking, standing jab whiffs against crouching
Cammy
Blanka
Chun Li
Vega
Everyone else will block the standing jab… You’ll notice that this list is really tiny. You can use s.lp in blockstrings pretty easily.
If they’re getting hit (during a combo), standing jab whiffs against crouching
Cammy
Akuma
Dhalsim
Blanka
Chun Li
Ryu
Honda
Ken
Viper
Rufus
Dan
Bison*
Vega*
Balrog*
Rose*
Everyone else can get hit by standing jab in a combo when they are crouching. However, this doesn’t mean you can just s.lp repeatedly either. It may only hit once and they can crouch the next. You’ll notice that this list is huge… It’s sucks that a lot of these characters will easily eat a standing jab while crouching, on hit and block, but if you try it in a combo where it matters (after a jump-in or c.lk), it whiffs.
*** Against Bison/Vega/Balrog/Rose it will whiff unless you time it slow/fast/close/etc. It’s really particular against those few because of their reeling hit-stun… You CAN hit them, but, it’s not for free.
Characters you never have to worry about whiffing a s.jab on are
Fei Long
Gouken
Zangief
Seth
Sagat
Abel
El Fuerte
Sakura (yes, you read right)
Everyone in the list above is standing jab fodder. It won’t whiff, ever.
Characters you can NEVER hit a standing jab on if they are crouching are
Cammy
Chun Li
Some special interesting cases are:
Vega - it will always whiff… EXCEPT in a combo, and only if you time if just right.
Blanka - if will whiff if he’s blocking and and it will whiff in a combo… but if he’s just crouching there, it hits.
Guile and Gen - it whiffs if they’re crouching, but will work in a combo. I guess their crouching hitstun if taller than their normal crouching animation?
