if they do a jump meaty fireball you can SA2 through it sometimes.
and yeah EX knee smash rapes demon flips as sanchez said.
i like s.hk vs akuma. kick the shit out of him if his stun gauge is 2/3 full.
at the right range you can f+hp and trade with his air fireball or dive kick.
he isn’t touching j.mp or j.mk air to air anytime soon.
alex jumping is still pretty good against akuma, just time and poke until you find a good spot though. make him poke back then jump, then be ready to parry his srk since he will most likely do that recovering from a poke.
overall the big bruskie here is disadvantaged. akuma’s offense is pretty damn good on him even without as much demon flip options. you wanna most likely wait til he trips then kick him while he’s on the ground, if you catch my drift
edit: oh and i like f+mp as an early anti air+poke when i have him cornered in a neutral state.
