You resort to a dirty trick

This girl is crazy you think to yourself. You’re determined not to play according to her rules. As you lock fingers, you’re surprised by her strength. She has nearly succeeded in bending your wrists, but you have a plan. You quickly raise your knee into her stomach and release her hands. You make sure your blow isn’t hard enough to do any real damage, but it has doubled her over.

You have the advantage, how do you proceed...
