The only way to win a street fight ill name You some..

[Esteban1997]

Rear naked choke (mma move)
Fist to the neck (pressure point)
Punch or kick to the balls (painful and effective)
Hard low kicks (works)
SIDE kick fast to the knee (you'll eventually break the knee if You do it fast and with power)
These are ways to win also krav maga is effective in a streetfight mix with boxing and wrestling moves
I don't encourage You to start a fight just for fun if You can evade it it's better but if You can't these are ways to win

 

[Saint Casanova]

Eye gouge,
Liver punch or kick.

Lifting your leg in a fight Will get You knocked out mostly because the other guy might eventually know when You do it
