I think we are all in agreement that keeping things simple is best.
It appears that SKK uses animal imagery and TSD uses similar defensive concepts to my own but without the image-inducing descriptions. TKD and Hapkido would appear to be the same as, or at least similar to, TSD.
What about Karate? Are there only one or two applications of a block or parry?
I'm not a karateka... but based on what I know about bunkai for the classic karate kata, and the way in which these kata were broken into `minimal combat sequences' and then recombined to form standard TKD hyungs, my guess would be, no—there will be many applications of a blocking
motion; similarly for a punching
motion. Motions and moves are two different kinds of things; so look at Rick Clark's book,
75 Down Blocks, which shows, literally, 75 different applications for the simple, classic down block shared by all the karate-based MAs. A blocking motion can be a strike (to a lowered head, to a carotid sinus, to a weak point in the attackers's upper arm); it can be an upward elbow strike (the upper chambering motion), or part of an arm pin using the elbow to estabish the pin on the attacker's trapped arm, followed by a downward elbow strike (the rapid downward upper arm motion) followed by a hammerfist to the aforementioned targets; it can be part of a throw, and many other things. A punch can be a punch, but it can also be part of a crippling or fatal neck twist (with the other fist's `chambering' motion the supplying the other half of the twisting force), as well as part of a throw, and so on. There are elegant, robust bunkai for kata sequences containing these movements in which one or another of these techs is a valid and highly effective interpretation. I'd have to say, one of the great things about kata, and therefore karate technique, is the elegant packaging, whereby four or five different applications are derivable for each motion (in the context of a similar intepretation of the preceding and following motion, of course).
The different again is semiotic: the karate-based arts don't use animal references to encode these respective multiple interpretations.
