Also against viper, lk jaguar kick completely stuffs her seismo game and feints. She has bad normals so abuse that too. Don’t be eager to press buttons on wakeup because burning kicks suck, but they are not always ambigious so just be patient. She can really kill you if she gets going, but you can rape her shit in a few JK’s too. Safejump her, I notice most players start to backdash once you do so punish that.
Against boxer, a low iAJK can shutdown jab spam, doesn’t always work but it’s very in your favor in the end. A stand MK also works. Rush punches can be focused or beaten with well spaced/timed roundhouses and fierces. If he does the armor breaking one you can punish it with lk jagkick unless he’s very far, if he cancels his rush punch into super I’m pretty sure backdash will make you airborne and not take all the hits. Safejump him, don’t go for crossups (well you can but don’t let that be your default behavior) because he can escape crossups with headbutts and shit but can’t do much against safejumps.
An important thing against boxer is to remember not to rely on zoning with jagkicks like you would against other characters. His walkspeed is too fast to space them well and you will whiff often so be sure he’s crouch blocking when you do them. Or in the corner (wary of headbutts).
Abel, punish wheelkicks with LK jk if you judge the distance is right, ex is safe of course.
His rekkas should be punished like this: First hit is throwable on block (ex included, but tighter). The timing is tight, you might want to plink your throw. So after you block the first hit, attempt a throw, if he does the second hit you will block it, now you can freely punish with a RJ, doesn’t matter if he does the third hit. It’s pretty hard to do it in matches and I still miss but that’s the idea.
Ryu: Punish sweep with st.rh, I haven’t found anything else reliable unless he does it very close.
Gief: A properly spaced (means that you land outside of SPD range) HK jaguar kick is effective on wakeup, lariat will get beaten and EX greenhand will go trough you, making him waste meter at worst.
Cammy: divekicks are a bitch, other than to focus the hit and backdash I haven’t found what to do. A jab might work bit it’s not guaranteed. Being in the corner is nasty.
