I already knew the answer to this? If I'm going to use a technique then I better know the limitations of what I'm using. One of the keys to be successful with a technique is to know when to use it and went not to. Knowing the limitations is also important because that's where your opponent will try to exploit it. So that information I already knew. I never had a question about that that stuff.
My curiosity was mainly if you other's here knew. And if you notice no one is saying they would try to take me down by trying to go under me. Which is the purpose of the stance, to cut that stuff out. But just because I close one door doesn't mean that another one didn't open.
Sometimes people get stuck on. One type attack. I like those guys because they don't look at other options. An example. TKD kickers are always trying to kick. They often for get that they have have hands and often times miss out openings that their hands could have taken advantages. In some cases, they are so focused on kicking that they sometimes forget that they can put up their guard using their arms. And how long did the conversation go on until someone said. that they would kick my lead leg? That same type of tunnel vision happens in fighting. It is something that can be taken advantage of and used to your benefit.
When I had wrestlers and BJJ practitioners try to take me down while in that stance not one of them thought about kicking my leg because of that tunnel vision. Is it my fault that they didn't think of it. Did I offer it as something they could try? heck no.
This is like a choose your own adventure story. How does one high level wrestler catch another high level wrestler with a single or double leg takedown? Once you've answered that question, you'll have your answer, too. I just don't get how you think a strong, low stance is somehow revolutionary. It's just common sense, so I think most people aren't saying it because it's a given. You're acknowledging a kick to the lead leg as some kind of good point, but when others point out that your low stance makes you vulnerable to other things, you dismiss it with a casual, "Like I'm going to let you arm drag me or take my back." or a "I'll just raise my stance." This is fiction. It's make believe, and it's seldom as clean as you're making it out to be.
I'll try an analogy. If a guy is defending an armbar, how do you submit him? If you're stronger and/or more skilled, you could just impose your will. That's probably the simplest way. Just go grape ape on that arm and tear it off, or exploit a significant disparity in skill level. Voila: Armbar in spite of the attempt to defend.
Option 2: Just submit him with a technique other than an armbar. Another simple solution. You can catch a choke, wrist lock, kneebar, ankle lock. If we're talking about a situation where strikes are allowed, the possibilities are endless. Point is, if bad guy is defending X, easiest thing is don't do X... do Y instead. In your thread, this could be leg kicks, punches to the face, arm drags, etc. I bet there are thousands of possibilities that depend on what I'm good at vs what you're doing.
Option 3: If you really want that armbar, you encourage him to defend something else and hit the armbar when he's defending something else. Threaten something else, and force him to move his arm. Similarly, if you're in a low stance and I really want to hit a double leg but can't because you're practically sitting on the ground, it's just like what you said up above... get you to raise your stance and then hit a double leg. We see this done all the time in an MMA match... threaten high with punches and kicks, and then attack the legs. And the better your double leg vs the other guy's take down defense, the more likely you'll get it the first try, second try or maybe not at all.
Getting back to the armbar analogy, it all starts with how good your armbar defense is and how good I am at hitting that armbar. But it's also how strong you are, how strong I am, how athletic you are, how athletic I am, how skilled you are at things other than defending an armbar, how good I am at executing other things... and also all of the above points in reverse, where you are the aggressor and I am defending.
