very interesting concept. i must have missed your video on this system a while back, but it looks to be a smart idea. i do try to do something different every exchange, or at least i'll only do something twice in a row with purpose if i think it'll catch my opponent out, and this is a quite neat and tidy way of formalising that. great final exchange btw, proving why zwerch is a master cut - attacking and defending in the same motion!
