Regarding Bison’s U2:
If you are waking up and have no meter, guess which way to block. He will probably try to cross you up with it the first time, and then if he does it to you again in a following round he will probably not cross you up if you blocked the first time.
If you are waking up and you have meter, EX SBK.
If you are just standing around and aren’t in the middle of a move when he does it, jump and airthrow (it wins if he comes close) or jump and do nj.HK on the way down, follow up with your combo of choice if it hits.
Regarding Fei Long’s Chicken Wing:
A lot of Fei Long players like to use it to get around fireballs, so something I am learning to do is bait the Chicken Wing from about 3/4 screen and U2 him out of it. Even the EX version doesn’t have invincibility that late – it’ll get around the Kikoken, but if he’s coming into an Ultra 2 there’s nothing he can do.
Regarding Blanka’s Electricity on his wakeup:
The safe jump is actually forward throw, dash forward, crossup j.LK. Unless you have the spacing and timing for that totally down, it can be difficult to do off a regular knockdown. Either way, cr.MK and cr.MP beat electricity pretty clean. I suggest cr.MK if you are close enough to combo, otherwise just use cr.MP.
Regarding Gief:
It gets easier for him to SPD Chun’s far HK if you get predictable with it. I don’t know if he was doing it on reaction, personally. I’m also not calling Wii a liar but far HK has 12 frames of startup. Claiming that a Gief can punish on reaction far HK then, means that not only can he read and process the startup of the attack, but that he can also perform the 360 motion and press the buttons, ALL WITHIN 12 FRAMES TIME. I find that hard to believe. Not saying it’s impossible, just hard to believe.
If he does it on prediction (which imo is most likely), there are two things you could do.
If he listens to your button inputs, hit other buttons when you would ordinarily hit HK. Watch for SPD. If nothing happens, proceed as usual. If he whiffs SPD, punish to the best of your ability (I suggest Ultra if you have it).
If it’s online or he doesn’t listen to your button inputs, dance around the max range HK can hit from and just try to bait it by throwing it out a few times and training him to look for it.
