I’m sure this stuff is very basic–stuff I’d know if I had the fundamentals of Ryu down–but here are some situations I haven’t figured out how to deal with. I lose to everyone right now, but in some situations I at least have an idea what to try for. Not in these. I’d really appreciate either guidance, or being directed to things to read. (I’ve been busily working my way through the general guides and materials here on the forum, don’t worry.)
Situations in which I don’t know what to do:
 C. Viper uses her Seismic Hammer over and over at long range with good timing. (Using my own ranged attack still gets me hit, defending accomplishes nothing, hurricane kick sometimes works, but not always…)
 Akuma launches Wrath of the Raging Demon. Even against poor players where I know it’s coming I can’t figure out how not to get hit by this.
[*] Grapplers in general. I can often land a bunch of blows, but the grapples do a ton of damage, and I’m not sure how to handle myself so as to avoid them or defend against them. Nothing I’m trying seems to work.
