Oh its been a while but lets see I can help you
After a mid screan power bomb I would usually partition a medium elbow slash (dash up elbow slash) this would hit kinda meaty, no big deal here, your opponent would block but it would seem that your opponent gets an oppening, so buffering a stomp here works most of the time, mostly against non stock chuns and kens.
When an EX elbow slash hits your opponent in the corner you can walk a little whiff a f+ strong then do an UOH linked to super, the distance is perfect.
Another thing I used to to do wasthat in the corner after a succesful st forward to EX flash hop would be partition a stomp, charge exactly while alex performs the ex flash, dash up (by this time they would exactly standing up) and stomp them.
hope that helps
oh and wait my best tip against chun
tap right , then down twice after highlighting alex on the character selection screan.
Best strategy ever ^____^
sorry I just had to
