I agree with david whole heartedly.
I have sparred a bit with taiji, which I know david does not approve of...
Even so, what I found was that if I did not make a concerted effort to use the movements as I trained in them, I would get torn up, because I was essentially street fighting. You build a foundation in training. Why do so many people abandon it the second they enter a fight?
It was hard for me to understand that when I tried sparring using taiji. Naturally enough, at first there was just the nerves and the adrenaline. It had been ages since I sparred, and so I just went in there and willy nilly tossed out some sorry punches and kicks. They may have touched the guy I was sparring every now and then, but hell if they could have done damage.
After a while, I began to wonder...
"Golly, I am getting schooled. Could it be because I am not using anything I learned in taiji?"
So, I began to try to throw brush knees, a high pat horse here and there, a palm change. Certainly they werent the most beautiful things on earth, but a watcher could have clearly watched and said "2nd change", "repulse monkey". And naturally enough, it was my first time using them in sparring, so it was rough edged regardless.
Even so I was still getting schooled.
Why, because the guy I was fighting was a wado-Ryu karate guy, who would bounce around at a safe distance, angling for opening, bounce in and bounce out.
Essentially, I was playing his game. I may have been using techniques from taiji and bagua, but I was not using taiji or bagua.
So I began to try to do more than just a technique here or a technique there. When Karate guy jumped in, I slipped behind him. When he tried to turn, I stuck to him. When he tried to back out, I read it and added the little extra to knock him off balance and apply a high pat horse to the abs.
Thats when I was doing taiji. Did he still hit me? Sure, but thats what happens in sparring. The important part wasnt beating him, or taking him down. The important part was learning to use what I learned correctly and effective, from the ground up.
I think this is the fundemental problem with the clips here. That being said, I enjoyed them. Perhaps a bit more explanation is warranted, though. I would never have known the guy in black was holding back because of bad ribs and a sprained toe, but I did know he was holding back.
