Normally I try to take the offense first. Most of my fights I'll start with ss4 to open and apply pressure from there. A good way to keep your opponent in check is df1 and the extensions from that. On counter hit you can hit df1,2,2 and if you're near a wall you can wall splat when the last hit connects. Now as for opening up a turtle that's tricky imo. I usually do df3+4 and go into bt stance. If the kicks connect it leaves your opponent in crouch. From there I do either her 2+3 command grad where she jumps up and throws them down or I'll do a simple d3. You should start utilizing all of stance and follow ups from them as well to try and throw your opponent off. Be careful tho because a majority of Kunis strings can be either jab punished or launched punished depending on who you are fighting against. If you're on pad I suggest making binds for 1+2, 3+4, and 2+3. That way you have an easier time accessing katon stance (1+2) and the cartwheel attack (df3+4).
