Most of Yun’s go to combos are at least 2f. He’s not an execution heavy character unless you want to style. There are some hit confirms you can use with cst.MP and select plinking but I don’t see them used much, if at all.
AE Yun didn’t have any crazy plink combos that I’m aware of, but doing command grab, walk forward, cst.MP xx EX Lunge was fairly difficult. It was relevant then because Yun would get U1 anywhere.
edit: Actually there is LP Shoulder FADC cr.LP/st.LP but I don’t know if those are optimal.
I actually got meaty cross up lp shoulder/meaty hop kick(I mean hit on the last active frame), cr. mp/close st. hp to connect on quite a few occasions.
I think non counter hit those are one framers but those aren’t really practical. If you see the counter hit though it’s really easy to link
Meaty shoulder is at least +7. Meaty overhead is +5. The overhead, cr.MP is probably worth it but I usually confirm with st.LP because I don’t trust my overhead timing. cst.HP is probably not worth it (the activation range on this move is terrible…and it only does 80 stun.)
Well you can plink those regularly without select plink at least.
depending on the speed of their normal (neutral LK dive)
This change affects matches like Cody, Rose, Balrog, Shoto’s, well majority of the cast to be fair.
On characters like Rog now you can jump after a blocked ex lunge when he tries to blast through with all ex rushes and headbutts EXCEPT for ex upper which just catches you, quite nifty when trying to avoid being chipped out.
Be wary because you still can get jabbed.
Hi I am trying to learn Yun and I have a few problems applying pressure to opponents.
Uhm, where do I start… I am having trouble crossing opponents up with divekicks, I think I don’t know how to use specially the low dive kick correctly. I have seen people do divekicks on opponents block and then they jump again and do another divekick. How exactly do I do this right and can this lead into a crossup?
The only setup I know is forward throw into forward jump, forward jump-divekick. Also the mp xx dragonkick, neutral jump mk against 4f quick stand wakeups. My problem is that my enemies never use quickstand after the dragon kick… Is there another setup I can go for?
The combo I have practiced the most so far is cr lp, cr lp, st lp, st mp xx dragon kick. I can do this one cosistently. Sadly this doesn’t work against Decapre and Poison since they seem to get knocked back further than most characters. Also this is clearly not his most damaging combo. What other combos should I practice with Yun and is divekick into cr. mp a true blockstring? If so, are there more ways to land a relatively safe cr mp?
It feels like I have to be way too close to my opponents to apply some pressure. Please help! (also sorry that this questions all have been answered before, but the threads here are so old and I need some fresh infos)
It all depends on spacing. A lot of yuns divekick stuff is annoyingly character specific and so are his bnb combos. It’s kind of difficult to explain the timing on divekick setups after upkicks and lunges etc but what you’re seeing is yun players using mk divekick at the lowest height. If you’re at the right angle it will cross up against a lot of the cast. You need to be careful though because it’s not hard to mess it up and get punished. Divekick crossups are nowhere near as safe and reliable as the typical j.mk crossup for most characters.
As for combos, the one you mentioned is the go to combo, however it is character specific. Heavy upkicks whiff on quite a few characters and st.lp whiffs on some of the older cast and most of the newer cast when they’re crouching so you need to have some variations. You’ll only be landing cr.mp full damage combos from big mistakes. You’re right though, with yun you have to be extremely close to be a true threat.
So it’s just practice, practice, practice then. I think my biggest problem is that I’m trying to go for unsafe divekick shenanigans when I get a knockdown. I want to apply pressure or cross them up on wakeup because I know “it can work sometimes” and then I eat a throw. I make the crossup work sometimes after a dragonkick with forward jump low divekick or neutral jump mid divekick but maybe I should try using j. mk more often. It was buffed for a reason I guess. XD
J.mk crossup is very setup specific, his divekicks are much better for crossing up, you just gotta practice. I have yet to see any top players effectively use j.mk while applying pressure unless it’s in the corner. Even those guys sometimes mistime divekick crossups, so don’t get to disheartened if you’re not good at it yet.
When I first started yun I did the same as you, I went for random divekicks after knockdowns hoping they would crossup because I had seen others do it and I usually got punished for it. Once you start practicing though you’ll get it pretty consistently in no time.
EDIT: Lk divekicks work very well too if you can time them just as the opponent is quickrising.
fyi I’m talking about this thread guys Unlisted Changes in USF4
unlisted changes in the current build of ultra that weren’t mentioned in the change log posted by combofiend. He claimes the range was slightly increased for command grab from AE2012-> USF4
After a knockdown, what do you guys usually go for? I’m afraid everytime I try to apply pressure on wake up. I get DP’d like immediately or wakeup grab haha. What’s something you guys usually go for?
