I don’t really use Sakura, but basic stuff with Ken & Ryu…
his pokes is cr.Forward, you can pretty much only poke- super with his level 3 QCBx2 super.
his anti-air is cr.Fierce, or let the opponent get deep in their jump in and then shoryuken. (Good to mix your AA’s up)
his poke is also cr.Forward, although his hop kick can sometimes be useful
his anti-air would be either his st.Roundhouse, or cr.Fierce, or shoryuken, same as Ken
her poke would be st.Roundhouse, her AA is cr.Fierce (Good stuff, abuse it)
I mean as far as basics, I guess that’s all you need to know before you start to go into B&B’s and linking into supers.
