I never use d.MK anytime when I play Chun. d.MP is just so much better. The only three moves on the ground I use versus cammy:
-s.MP. You can freely poke with s.MP xx any strength fireball anytime you want against Cammy. Her roll is too slow to punish it and the block/hit stun from the MP makes it so Cammy can’t drill under the FB either.
-d.MP. Use this when Cammy levels gaps in her attack patterns (even though those gaps are infuriatingly small sometimes). After a blocked close s.HP for example. Chill for the 9 frames or whatever until the block stun wears off. Then if Cammy tries to walk up and close s.HP again, you can counter hit her with d.MP if Cammy so much as flinches on a button.
-RC HP fireball. This move is so good. I had no idea! (until I could actually do it without messing up half the time :lol: ) You get the frame advantage when it’s blocked. Even better when it hits (ie. you went through Cammy when she tried to s.HK you). Just don’t whiff it that’s all. Even though the recovery feels like it’s close to zero practically, a good, non-scrub Cammy can s.HK xx super you after.
Don’t try to cross Cammy up with Chun too much. It’s difficult with Cammy’s walk speed and small height.
d.HK everything Cammy does from the air too. I even d.HK against dive kicks. Against Sakura, I run far, far away… but against Cammy, it’s OK.
