man that is a good point what about keeping constant pressure on him with lp flash chop and lk smash elbow how do you think that would oh can the anti air knee drop be parried
I did it yeah
the secret is running away 
yeah, I just realized, that once they have a good genei jin set up (3 hit string (blocked), throw etc)if you block low, the only things they can do to hurt you are:
command grab
f.forward
dive kick
UOH
now, yun will disguise his command grab and stuff, but keep this in mind, if he not poking like crazy and you see him walkin, he might go for either a command grab or he is tricking you to stand up to make c.short, palm etc
to get out of this, theres a real easy answer, c.Jab!!!
yeah, when he walks, or when his f.forward is starting, c.Jab will make him stop
seeing the way youre playing, they will try to mix up, and dive kick or something, heres when you can get out from wherever you are (corner mostly) since he is specting you to make the c.jab no te get out
you can change from jumping to dive punch (d.fierce) or just dash out (when he jumps) just be careful
now, yuns meter is empty so is your turn, mix ups are EVERYTHING you got
later
dude thats some great advice, most of the times i just block low and wait for a parry opportunity (usually i parry the command overhead). ill try that, although the yun player might try to walk next time but doing another string which will beat your c.lp i think (more priority/speed i assume). anyway good tip.
well yeah, yun will mix up once he sees you doin it
but Im telling you, if your move goes out first and yun is walkin he will be stoped 
So c.jab to try and stop the poke attempts from Genei-Jin…good stuff. I was recently beaten (kinda badly) by a Yun a week ago…got rushed down by his Genei-Jin. With some time, I’ll have him countered out and what not.
very helpful advice I’ll try out next time I play a good yun
you know, if he grabs you mid-screen, he won’t deal much damage. however he will get half a bar back.
If he likes to dash back then activate, just jump up when you see him activate from far and parry the shoulder or rush punch. If he walks forward, then just block and he won’t deal damage cause his bars almost gone.
Ummm… Block Low, Watch for Command Grab, and Cr.Jab. Like they said
Oh also you may stomp when they jump
like KSK did it on evo 2k5
once yun jump, stomp
they might spect it and stand up just to block, stomp right after landing again (buffer)
a nice mind game
Yeah, you just gotta stick it in the corner and CROUCH BLOCK and wait for an opening. If you see an attempt to throw (if he tries to walk towards you for mix up during Genei Jin) do it. I always like to stomp on him ala KSK as well. Good stuff. Just turtle it up once he activates Genei Jin and just wait for him to make a mistake. As strong of a character as Yun is he has to take risks to get in on you and that’s when you can take advantage of him. Parry any random dive kicks and punish the best way you can. For a top tier Yun has very low defense so one or two good mistakes from him can give you an opportunity to turn things around and win the round/match.
