So much bad advice in this thread. The best way to beat up kicks is to bait them. It doesn’t matter where he lands, if you have meter, you will punish him hard.
Jabs, st. MK, and Fierce punch will beat every single dive kick from range.
You can’t rely on focus in this matchup at all since he his best poke (St. MP) can be hit confirmed into target combo. Best bet it to take your first opening and PRESSURE. Don’t just press shit, concentrate on baiting out random up kicks. If the Yun doesn’t take the bite, it means he’s blocking, and if he’s still blocking, you’re winning. Whoever can dictate the flow and maintiain pressure is the one will win the match 10 out of 10 times.
And if you’re not using U2, YOU’RE DOING IT WRONG
It BLOWS UP Ex rush and BLOWS UP dive kicks. One properly timed U2 can completely turn around a match.
Why anyone would choose U1 in this matchup is beyond me…
