Nope, the thing with both 3KK and 2KK is that if you guess the first kick right, you can duck the second one (if he does not hitcheck and not do that on block). After that you are free to launch him. There's a plethora of options to go for from 66P, I'm pretty sure they are listed on the Jean forums. 43P+K is not really that strong there. 66P+K you can punish with a throw attempt on guard. Both 1K+G and 2K+G can be punished with 4P for a combo (though 1K+G does have phonomenal reach, not sure if it works from max distance). 2K+G can also be punished with 6P+K for more damage. Backdash is usually a pretty safe way to start a round most of the time. If your opponent has obvious habits in his round starting then you can swith do doing something to that particular thing.
