This is the shit that will get you disqualified... or arrested. Save these moves for street fights.
Elbow: thrown with hand open and arm tightly folded, as if trying to hold a marble in the crook of your arm. (think of a chicken wing) Can be thrown as an uppercut, in a downward arc or horizontally. Thrown primarily with shoulder. Can also be used as defense. Elbow can be thrown at or placed in front of incoming punch.
Hook & Elbow: a hook followed immediately by an elbow. Mike Tyson used to get away with throwing these quite often. The punch looks like a tightly thrown hook, but actually it's two blows in one. You land the hook like normal but then extend your shoulder slightly and pivot so your elbow comes around in the same arc and lands where your fist did.
DeadArm Punch: a wild overhand punch thrown with the rear hand like a person pitching a baseball.
Headbutt: every martial art of African descent has this move in its arsenal. The 'big knuckle' is a good offensive and defensive weapon. There are several prime striking areas to use when headbutting. The upper forehead (where the hairline begins on most people), the left and right corner ridges of the skull and the back of the skull can be used as a weapon against someone behind you. Your head can also be used defensively against punches. When a straight punch is coming, tuck your chin into your chest and take the punch on top of your head.
Low Blow: In boxing rules, any punch below the navel is a low blow. In a street fight, you automatically think of the groin as an ideal target. It is, but it’s not always as effective as you may think. It’s often hard to land a solid blow there. If you get the shot, take it, but a more practical target is the lower abdomen. The abdominal wall is weaker there.
Rabbit Punch: This is a punch that target the back of the neck, a very vulnerable part of the human body. The back of the neck houses several nerve clusters and a punch there can produce a KO.
Put Bone On: a 'defensive attack' in which you attempt to injure an attacking limb by blocking/attacking it with a hard part of your own body.
Twirling Elbows: a rapid sequence of arm movements around the face and head that serve the duel purpose of protection and hitting anyone that gets too close.
Comstock Lock: a move in which your arm clamps down over a punch, trapping it against your body.
Pants Leg Grab: a takedown move in which you grab the opponent's pants leg, around the ankle or knee and snatch back and upward, sort of like pulling a rug out from under someone. A shoulder bump into the opponent's midsection helps to throw your opponent off balance and grabbing the pants leg should take them down.
Wall Fighting: an aspect of Jailhouse boxing that separates it from other fighting styles. Wall fighting turns being cornered or backed against a wall to the fighter's advantage. For instance, if a punch is thrown at you while you're backed against the wall, evade the punch so the attacker hits the wall. You can also grab your opponent and slam him into the wall behind you... and wall fighting gives you the added advantage of knowing that nobody can sneak up behind you.
Changing Levels: although there are no real kicks to speak of in 52, there are low level attacks. These attacks are made with the hands and elbows but you must change levels to execute them. Changing levels is simply bending at the legs (never bend over at the waist) and lowering yourself to make these attacks. This is a 52 tactic that is really confusing to the person you are fighting. By changing levels you can punch areas that are normally only attacked by kicks, such as the groin and the thighs.
