From your description, my guess is that a lot of the grappling that you've been trained in is more of the hapkido/aikido variety. Honestly, I don't know much about throwing from a wrist lock or that sort of technique beyond what I've seen in demonstrations and whatnot.
Im gonna have to disagree. Having seen Hapkido, this is very little like it. I think Ive learned two Wristlocks, and theyre for use after taking someone down. Not as a setup. Im talking about literally grabbing someones Arm with one hand, and most of the time, their Torso with the other. Failing that, their Neck. It just happens to be easiest to grab the Wrist instead of the Forearm. I have no bloody idea what thats akin to, but then, I dont really see a need to read into it.
In judo, we talk a lot about "kazushi," or unbalancing the opponent. In fact, when two judokas go to war with each other, the first part of battle is setting your opponent up for a fall. That's largely what all the pushing, pulling and yanking is about before a throw happens. You're trying to take away their base so that you can successfully execute a technique. You have 8 directions of kazushi--front, back, the sides, and the four angles.
Aye. The Hand on the Torso usually pushes.
If you have someone on one leg, they have already done most of the work for you in achieving kazushi. Their base is severely compromised. There's no need to chop the leg out from under them because they're a top heavy object. You merely need to push or pull them in any one of the eight directions to get them off balance and successfully execute a throw or takedown.
This is actually My Point The Takedown is no different to any other Takedown, in that its their Upper Body Youre taking down, mainly.
If you watch an MMA fight, kickboxers are much more reticent to throw a kick when fighting a good grappler because it's much easier to defend the takedown when they have both feet solidly planted on the ground.
As I said - Kicks are easier to Grab. Id just say its harder to actually do the Takedowns from there. Its like a Thai Clinch. Im interested to know why either A: Uppercut Flurry or B: Punch the Rising Knees at the Thigh to try and get the Nerve; Never happen.
Personally, when I did judo, I never did get great at executing a lot of the high-level throws against resisting opponents. If I had stayed in it longer I'm sure I would've gotten better, but I was always a lot more comfortable with clinch throws, like the hip toss or more greco-esque stuff like getting my arms around them like a bearhug, dropping my weight underneath theirs, and then picking them up and slamming them.
Personally, I tend to be good at Grab > Hit > Takedown. I can do Throws, but its not exactly a specialty. Most of it comes from Physical Strength more than skill, which perhaps isnt the intent
I think that what I would suggest for TKDists is to make sure you are comfortable if someone closes the distance. Since there's no clinching in any style of TKD, and no face punches under the WTF rules, it's easy to get used to not having someone up in your face. When you go back and watch the early UFCs--when it really was style vs style--grapplers were always able to close the distance eventually, and I think that even a motivated and aggressive brawler stands a chance of timing his attack right to get into a range that takes your kicks away.
Well, theres illegal clinching in WTF Sparring And ITF Sparring for that matter. In all relevance, Yes. I absolutely Agree that its pertinant that Youre Comfortable up close.
