Been playing a shit load of this match up recently so...
-Ib chains whenever possible, its like a free anything if they chain in.
-houtenjin beats 214d~a and b so if you have meter and see one coming It's a free FC.
-If they whiff a chain and chain in with D you can easily get em with 214d~B
-Bait those chains
-I feel 2C anti air is somewhat unreliable in this match-up, it's just too slow. I say stick to 5a is the go to Anti Air, but that's me :/
-Watch out for command grab, It's the one thing that gives haz decent mixup.
-C follow-up can usually be stuffed by 5a.
-Keep your pressure safe and varied, abusing stance leads to getting houtenjined. You got 5b for a reason, use those frame traps.
P.S. Don't be free like me :/
