Against Ken f+mk, roundhouse beats it clearly from a distance, hk jk can be good in mind game and rj in reaction if he really spam it, if he plays with U II use hk jk in mind is not the best idea.
Most of the time i use avalanche against Ken, his hadokens suck to much to be really useful.
If he had two meters to cancel, just block, it’s better to eat a throw than dp cancel to ultra.
His air tatsu is really annoying to me, so much priority in air and if it hits in ground, it’s hurts, sometime late rj can anti air this.
You can check the final between GamerBee and Momochi, really greats matchs or those against Daigo’s Ken, it’s really hard for GB.
Against Cody, don’t jump, don’t spam jk, you must play smart and put it on the ground to win, rj every jump, you can OS U II against his backdash and (ex) zonk.
Neutral jump mk cancel jk works very well against him.
Rose, rushdown her face, don’t play footsies, she’s better, easier said than done, she doesn’t have goods answers against jk except ultra I and slide, i prefer to use avalanche against her.
Akuma, pray if you touch the ground, he has better pokes, against his roundhouse, neutral jump hk, otherwise block and block and feel the pressure.
Balrog, i hate this match-up, roundhouse, rj or avalanche in his damn dash punches, take care of his damn sweep, don’t be predictable with your jumps and roundhouse, otherwhise you will eat an headbutt.
Bison, his roundhouse is just too good against Adon, play footsies until he touches the ground, try the good OS, if he doesn’t have and ex, i guess he will tp then os lk jaguar kick.
Some scruby Bison likes to jump with mp to juggle his ultra, rj this stupidity, there is a lot of matchs between GamerBee and Isy.
Against knee press, in the guard, don’t backdash, his roundhouse hits Adon’s backdash.
Don’t forget to tell us how it went.
Edit : Thanks Negro for the link, so many matchs to watch.
