Ok, im gonna break this down because i know some about it, and i know how hard it is for someone to pass in mma that doesnt know how to strike.
Passing MMA
tip #1 Whenever your opponent has you in his closed guard, hes just saying "Let me hold you while you punch me." The closed guard is pretty much useless offensivly in mma. Some guys are good at holding an opponent to get the stand up, but its looked down upon. The easiest way to open the guard that I have found is to bring your head up and your back straight, but still put your weight on his hips to slow him down (with your hips, dont put your hands on his hips!!!), and so you dont have to worry about being off balance for a sit up sweep. Now there are 4 major punches that you can do from the guard, the hook, hammerfist from above, hammerfist from the side, and the straight. The downsides to the punches is that if your weight and technique is wrong, something bad can happen for each one. The hook = triangle choke hammerfist from above = take the back hammerfist from the side= armbar and straight = armbar.
tip #2 When striking from the top position in the guard, the bicep is the major muscle exerting force and causing impact (for short hard shots that get people to open their guard, not KO guard shots, that involves much more muscle). Always try to punch like your a t-rex, keep those arms in close if your just striking to open his guard. If your trying to knock him out, you must be more open and looping, ala Fedor, but thats not what your trying to do.
tip #3 walk your feet up, so your butt is in the air, your knees are slightly bent, alot of your weight is on his hips, and your looking straight down into his face. (Mark Kerr was a master of this position) Rain down blows, he must unlock his legs for him to do anything. You want your knees bent because if he goes for the ankle grab sweep, you can drive your knees foward, rendering it useless and hit him in the face. And when I say knees slightly bent, I dont mean in this shape ">" the feet are the farthest part of your body back, your weight is on his hips and thats how the sweep doesnt work on you.
tip #4 once the legs are unlocked, grab hit foot at the bottom of his shin, and push it underneath your hip, then come back down. He should have half butterfly guard on you now. Take the hand on the same side of the trapt leg (you trap his left leg = right hand and visa versa) and place it on his knee of the trapt leg. Now take your head and put it to the opposite side of the trapt leg. Push on the leg, holding the leg in place, and bring your hips over his leg. You should blow by his guard. This is easier if you throw your bodyweight in the air and come crashing down on his trapt leg, minimizing his chances of getting guard back. I hope this makes sense. Ask me if you have any questions on anything. This is my mma pass I use all the time, minimizes submissions for the bottom guy, and doesnt make you too venerable to strikes.
wat do u normally do w/ ur other hand? under hook/ overhook the arm on the side ur not passing? just asking cause this pass sounds pretty effective.thx.
