His s.jab , walk forward s.jab/throw is a good mixup. You have lots of time to walk forward after a blocked jab.
For ground cc I like to do (c.mk), c.fierce (x1-3), c.roundhouse, s.roundhouse, (shoulder, palm) x N
Off of a close s.mk (ie a meaty attack, or activate close s.mk) xx sj.mp, (land) close s.fierce xx shoulder, palm, shoulder etc…
I like to do random shoulders.
s.short and s.mp are my favourite footsies moves. I use them to help me get into s.jab range. Also like to use the jab lunge punch and fierce shoulder every now and then to give them more to think about. (Same with s.roundhouse and c.roundhouse).
I like to walk into their range and then immediately sj into lk/mk dive kicks. Or at least i like to try to. It can set up a cc activation or at least get some damage or force them to block. The main thing here is to try to counter hit limbs.
His c.jab has a more reach than his c.short, so I start off combos with c.short and do the last hit as c.jab. If they block it all you are still in s.short range so depending you can get a counter hit short, and use it to keep pressure.
