Spinning wakeup kick punish
This is the optimal punish at the wall for that wakeup kick. if you hit SEN 2 on backturn, you get a guaranteed df1,2 at the wall, and most of the time they should turn around so you get a guaranteed wall splat.
If the wall is too close, and the second and third hit hit them when they are already against the wall, then they will turn around early. in that case you can just do ff2, SEN2, into df1,2.
Mind that at tip range it's only -16, so youre better off doing something like f2,3, SEN1+2, HW3+4.
