Well, I move out onto a 45 to the side which they have the leg raised on.. i.e. they have raised right leg I move off to their right and deliver the sidekick at a 90 to that direction (i.e. 45 to MY right). Makes it hard for them to retain balance if they are inexperienced, because often as you move they kick straight in front, initially, then perhaps realize the technique needs to be sent to their side, but it is harder to change direction on one leg and it's (obviously!) less stable. With it being the other side to the standing leg, it's harder to regain balance even if they bring their leg down quickly, because the momentum is such that their c-o-m is moving outside the 'platform' they are trying to make, unless they step it down behind them. 3 - 4 feet? Hmm. I was exaggerating, I think LOL More like a foot a so away, really, basically onto ****. But at the least, if it's pulled off they are in an awkward stance ready for you to launch something else. It does rely on speed and also, probably not going to manage it repeatedly, although messing about with a friend I did (but we'd both been drinking). At the absolute least, if they stop the kick it ought to still worry them that you got around the leg thanks to their reduced ability to move and turn (stably at least).
The thing about SD vs Sparring? I think I was just thinking out loud. I realized relatively recently that I was seeing sparring in that way. Perhaps because of where I came to MA from anyway (i.e. looking for the SD aspect over anything else). It was more my mental attitude than a fault with the instructors, per se. I had not really managed to separate the idea of 'sport' and 'SD' within TKD. As for relevance in this thread.. 'Flaminco' or whatever you wish to call it CAN be made to work, for points sparring at least. But it'd be a really stupid idea in a "real" fight was I think where I was coming from.
Now, I know this bit is no longer in your post.. but it is in my inbox, so I'll tackle it anyway. Biting as an effective SD technique? Sure it is part of it, if you are unfortunate enough to wind up in a hold and can bite somewhere, I'd say do it. Bar fights? Not really, but after leaving nightclubs, sadly a couple of times and witnessed both far to often (I used to work behind a bar as a student and even did some 'door work' during that same period). Dog attacks? As stated in the thread which you must be talking about, aside from an overly enthusiastic pet, no dog has tried to attack me. I may have even over-reacted in that instance, since I don't like dogs. However I have seen real footage of them, as well as seen, firsthand, dog packs dealing with small animals.
Pedantic? Me? Never! ;Ā¬)

P.S. "Ah. TKD sucks for self defense rears its gnarled hoary head yet again..." (quoted from my inbox) Now, why would you think I might say that given that TKD is the core of my Martial Arts and the only one I'm interested in 'belt chasing' in, as it were?
