Yeah, so we haven't had a sweep ever since I started this journal.. SO.. here's a scissors sweep. Sweeps are an integral part of jiu jitsu for a couple of reasons.. One: They put you in a dominant position. Two: They force your opponent to defend against them (for fear of losing dominant position) leaving you able to transition to a submission attempt and vice versa..
There are a lot of pics to go up so, lets just cut the bullshit and get to the sweep.
Scissors Sweep
The scissors is commonly used to drive an opponent off his base and force him forward or he gets sweeped. It is attempted when you are playing guard.
In this picture, Skinny Zack is inside JBizzle's closed guard and Zack is not in a set posture.
Justin shrimps in, placing his right leg parrallel across Zack's abdomen, at the same time, he controls Zack's head with his right arm and traps Zacks right arm with his left. (If this was gi, justin would control a lapel and not the head for better leverage and grip.) Justin is going to sweep to the same side of the arm he has trapped.
To sweep, justin pushes his right leg across zack's body and uses momentum to swing his left leg through zack's body. Try to picture a pair of scissors opening and closing. HENCE, the NAMe. (jiujitsu is very appropriate isn't it?) the hardest part of the sweep is most likely controlling the distance between your opponent's hips and yours. You do not want to be too tight as you will not have enough strength to push him over and you dont' want to be too loose because you will lack the leverage to even attempt the sweep. I guess, just try to feel it out and learn your distance.. it is fairly lenient in terms of distance so yeah. It doesn't take much adjusting to get it to work.
At this point, the guy on top can do many things. He could try a sweep counter but sometimes they aren't quick enough. Instead they try to drop base low so that they are hard to be swept.
Here Zack has dropped base to prevent Jb from sweeping him.. it is possible to still get it here but, Justin's hips no longer have the leverage to easily make a sweep possible.
To counter this defense, JB puts his left foot on zack's right knee.
He then pushes forward with his left foot as his right leg continues with the scissors motion and zack becomes top heavy and is swept.
Here is Justin mid-sweep. AS you can see he maintains control of the arm, this will allow him an option for submission once he maintains a dominant position.
Zack on his back and JB working on a mount. its good to actually finish in a controlled situation. This isn't. Try to base out and maintain a mount first. So yeah, this pic is just to show that he has completed the sweep to a mount. Usually, you get a side mount control, in this situation, he has rolled over completely into the mount. The main thing is, keep control of the arm and drop base so that your opponent doesn't get a quick escape.. all that work to just have your opponent escape would really suck.
So that's the scissors sweep with a lot of minute details left out.. its really hard to get each part of a sweep on picture as it is dynamic and fast. A good way would be to post a video clip. If you know how to post vid clips on livejournal, let me know and I will have some of those up.
