I agree thats my argument every techniques has a counter, so why stop using something thats working until they stop it, then youcan lure them into a counter for their counter.
Rarely does this happen in fighting but sometimes in sparring an equally skilled fighter, the counters can go for a volley and you step away admireing each others abilities. And it really becomes a chess game or Cat and Mouse, one mistake and you're looking up or down. The good thing its sparring and you can try it again and agai until youget right.
I agree with your explaination, I think Praying Mantis, Choy-Li-Fat, Kempo and may others system have this technique in it, wheather its known/taught or used is another matter.
