There are many ways to go about a fight.
Sweeping her would be a good option.
Quickly slap her in the face, this will stun her for a second, then without wasting anytime, quickly step your one leg behind her and at the same time pushing the heel of your palm under her chin, causing her to fall on her back over your leg that is behind her legs. When she hits the ground you can kick her in the face or ribs.
If you can somehow get a hold of one of her fingers, hold it tight and bend it back, until she screams for mercy!! You could break it, but that's up to you.
Try to avoid violence, but if your forced into it, make sure the fight is finished as quickly as possible.
Even if your not a martial artist, you might be able to execute these simple moves that i have described and prescribed.
