We do this slightly different (I think I need a hot key to type that)
as we step left foot to 1030 we do a right inward block followed by a left outward block, then step right foot 1030, a left ridgehand to the front of the throat with a right thrust punch to kidney area (gb25), bringing them back across the knee as we clutch the throat with the left hand.
Then after the series of strikes we twist the neck (left hand pulls chin, right hand pushes back of head) as we pull the knee out, so this is one of the very few techs in our system that could be fatal so it comes with lots of discussion on legal and moral issues when it is taught.
"as we step left foot to 1030 we do a right inward block followed by a left outward block, then step right foot 1030"
I got this wrong too! must be contagious. it's right to 1030 (twist stance) left to 12, right to 1030 (pivot). I hope that makes more sense.
