Well first of all I would like to capture for you people the main guiding principles used to win in street fights as understood by an ex con who also knew a thing or two about fighting and so wrote an ebook on the subject...
To win a streetfight you should...
1 Attack first
2 Get the first strike to the face or neck in
3 Be the dirtiest
4 Be the most aggressive and intensive
5 Be the one more concerned with attacking and offence
6 Use the most force intensity and aggression
7 use a weapon
8 Stay ontop on the ground
9 connects with the most strikes and cause the most damage
and 10 be better physically conditioned and prepared.
The last (proper) fight I got in, was with a woman at the hospital back in 2009. She came at me punching and kicking, so i grabbed her took her down, hit her once in the face with my weak right arm, and twisted her ear. Conforming to at least some of the principles displayed above.
