As Dime, Dae, Az and many of us will tell you – this is a very challenging matchup which we find entertaining; but it can be frustrating too.
It all comes down to the player that:
a. has better mind games.
b. has more consistent execution
c. possesses a solid understanding of her attributes/weaknesses.
What exactly are you losing to? Most chun “scrubs” as you call them are probably just using tactics you don’t expect to be abused so frequently.
The typical Chun player starts out by throwing a kiko or retreating to the corner; this pace will go on and on until you decide to go on the offense or they take the risk of getting free damage.
Aerial attacks almost always are initiated with j. fp x 2; hit confirm leads to cr. fp, concluded by m. sbk – this is not a scrubby tactic. If you’re getting owned by this, that means you’ve allowed them to enter your space when you could have punished them with an air grab, standing rh, standing fp or neutral st. mk…
Many Chuns recognize they can quickly keep someone off them by spamming shorts. I refer to this as “birdpecking” They know it isn’t going to lead to a larger, damaging combo, they just wanna keep you far away from their hit box. You’re best bet is to zone them with safer moves such as st. fierce or st. strong (which should be used a LOT). If you’re good with the latter, tie this into a medium or fierce kiko.
Also, watch for short, short, EX legs. This is a core fundamental combo that every Chun should utilize. The more skilled Chuns are capable of following up with Ultra, depending on their distance to the corner. Make sure to keep an eye on their meter to avoid getting baited into easy traps.
Avoid using EX SBK for every wakeup situation; especially if they’re good at knocking you out of the attack. Sometimes it’s best just to use the quick recovery command and backdash to get your bearings instead of feeling that you have to immediately get back on the offense.
Hope that helps – more specifics on what exactly they’re using to take you out would help the Fellowship be able to assist you.
