Someone ought to get ball rolling, so I went into the lab and tried some stuff out.
First order of business is dive-kicks. Badly spaced ones are easy: You pick a normal, and it will probably anti-air them. From one character-length away or so, stand jab or strong is pretty good for a quick fix, or low fierce. If he’s right up in your grill, generally it was easier for me to s.MK. Low fierce got beat a little too often in that scenario, though. If he’s getting too obvious, you can LP jet upper into your juggle combo of choice. EX cross counter is always a good tool.
Next: Special moves. All varieties of up-kicks are free on block. LK up-kick will whiff if you’re ducking, so start s.HK as he’s coming down. HK up-kick sends him a little farther, but it’s not too hard to take a step back and then hit him with s.HK. The stronger varieties (the ones you block) are punishable with either ultra on the way down, too (LK is too, but since it whiffs, the timing is tough).
Palm is safe, and difficult to duck through, but you can hit him out of the startup or U1 on reaction.
No good Yun will throw out random shoulders or poorly spaced non-EX lunges, but obviously they’re all unsafe (except jab shoulder, detailed in thread), so punish accordingly. Jabs can stop lunge punches, and if they DO like swinging the shoulders around, a reaction c.MK will knock them out of it (or, occasionally, trade). You can also react to both with Ultra.
For the poking game, Yun has a pretty powerful weapon in s.MP. Dudley more or less has to work around it. As always, f.MP and s.HP are your friends. c.MK beats all his low pokes clean and is generally a useful tool for the occasional knockdown. f.MP beats the low pokes too.
Yun, of course, is an all-out offensive machine, much like Dudley is. You both have the same general goals: Get in close, keep up the pressure, mix them up, knock them down. Use this to your advantage. Yun has low health and stun, so it should be pretty easy to knock him out if you get to work. I’m not a great judge of matchups, but this one doesn’t seem too bad. I like Ultra 1 because of the damage it can inflict, and it can deal with all his specials.
That’s what I’ve got. What do the rest of you think?
Edit: Great Yun info in this topic: Notes on Duo and Trowa
If there’s some easy way to merge these two threads, I’m all for it. Is this linked in the stickied matchup thread yet?
