This is what I’ve got…
Any dive kick - crouch tech the first two followup hits with c.mk as it will stuff any rejump dive kick attempts before they get started.
Lunge punch - punish with forward throw.
EX Lunge punch - crouch tech with mk. It will stop a throw, block if he does cr.lk and will stuff a divekick before he gets high enough to do one if he tries it.
Shoulder slam: Focusable/Kongoable with MP. Can try to bait it.
Use c.lk to stop the target combo counter hit bait. This is basically when they have you in block stun off light attacks and they seem pushed far enough out of range that it is safe to throw something out but then that retarded st.strong > HP target combo comes out stuffing you and giving them a combo.
At full screen if you can keep him there just fireball away, if he starts absorbing them do a HP palm to hit his recovery. If he starts neutral jumping with a dive kick you can use MP to smack him out of that
Any telegraphed dive kick or a jump that looks like it can turn into a dive kick can be stuffed with st.hp at minimal risk to yourself for 120 damage.
A lot of Yun’s I have played like to do the two handed palm on your wakeup which pushes them out to a safe distance for any of your grounded normals. They will usually immediately jump right afterwards and come back down with a dive kick.
This is what I came up with in the training room last night but haven’t put it into match use so use at your own risk. You can do a few things as soon as you see them jump. LP/MP Kongo will beat a MK dive kick and if LK divekick works I assume it will bebeaten by LP kongo, so if you want to kongo, use LP. Next you can just diagonal jump with HK, because of its arching hitbox it will hit them easy. You can also do dj,mp into tatsu but this can whiff, I’d hesitate to use it. Another option is EX tatsu. You can almost do this psychic/reversal as the hitbox extends out pretty far and will hit them regardless of whether they divekick or neutral jump. The other three tatsus all do different things because of their weird start up and nonsucking.
