from what ive gathered:
good kens ive seen try to avoid jumping, unless they want to cross u over. they know spacing, and will continue to pressure u w/ ups and down, especially w/ his mk overhead. do not abuse c.mk. its easy to see and parry and good players will expect it and, and then u will eat shippu.
do not try to punish a standing mk when blocked. they can parry after, its a common trap
its risky to punish ken dp’s because of how fast he recovers from them, however not everyone has the timing. watch out for super after dp. if u time it correctly u can get a fierce EX Hayate reset after a missed dp.
ur advantage is your dash and hayate. any time u see a roundhouse, and your at least mid screen away. can punish him w/ a hayate. with the exception of his c.mp. you can take advantage of his recovery by dashing in and throwing, or if you’re quick enough, dash in with a c.lk x SA1(thats the super i use).
fukiage is useless unless he jumps alot. ken’s moves dont overlap you so EX Fukiage won’t work in many cases.
master a short jump EX axe kick for throw happy kens. i believe it can hit them crouching as well.
a ken that tries to combo the super are very easy to parry, because anytime u are close to them they will start w/ strong, then fierce. if u parry the first two hits the fireball wont come out. however, they can learn and throw out the super straight up, and then you will be punished.
kens that link SA3 off c.mk are harder to deal w/ IMO. learn spacing well, and force them to throw out c.mk’s because they become happy about it. if they wiff it u can punish them. if u wanna be risky about it. dash within ken’s low kick range, and then go for low parry. i believe the recovery is quick enough to allow you to do that.
for some anti-foot poke shoto goodness:
ever notice that when shoto pokes u w/ low hits, theyll go for more than one, along the lines of c.lk, c.mk try and catch that pattern, cause it happens alot. if your quick enough to notice the first hit, then parry the second one, it takes time to learn, but im starting to get the hang of it, and it only works well for shoto, because of how easy it is to see.
yea… good luck vs. ken, hes a bitch.
