ok first thing is, Make a fist look at were its Straight, for me its the first 3 fingers. put your thumb in an L shape under the fingers ( after the nuckle comes a joint, just under that so it doesnt get in the way of the punch.)
First place to hit them if there not expecting it is the Stomache... This makes them Bend over and it alows you to get some free Rabit punches ( Hits in the back of the neck, VERY painfull) or an elbow to the back, or you could even kick the face in makin them loose there teeth very easily
)
if you are in a 1v1 were your both holding up fists i suggest you Jabb them on the Left or right Jaw side.. Hit as hard as you can if you know you wont miss, a normal punch hurts it doenst have to be hard.. ( idea of Hitting the jaw is to Twist it so that your head twists Knocking you out..) and a jab is a quick Punch to the face alowing you to keep back and get a nice Hard hit.
Dont think slapping is for pussies.. a Big Slap really hurts if its cold, especially this time of year.. if you get an oppertunity Slap with your whole hand, Dont spread your fingers just keep it firm, and hit As hard as you can, Followed by a Jab or an uppercut..
Gl, also using Surroundings is an option
this helps alot.. Sand can be thrown into eyes, You can bite them or even use water to your advantage.. there is alot you can do
i suggest you Have a fight with some Pussy to get you ready for the real thing
