He felt Mara move before he saw her somersault underneath him. Quickly he brought the blue blade up and began parrying and weaving through her attacks, trying to find an opening. His eyes narrowed some when he realized that making an opening in Mara's form was going to be close to impossible with only the use of his saber. He kept a grin from his face. He wanted to see if Mara was as good a Jedi as she seemed to be.
Letting her batter him back slightly, he took a step back with his left foot. Without warning, he suddenly slammed his left hand forward, sending a strong Force push at her. He ran after the wave of Force energy, eyes narrowed in focus. Along the way he gestured at an old wooden pallet to send it in Mara's direction to distract her as he closed in to attack.
Hopefully she wouldn't mind him upping the duel like this. But this to him was the only true way to showcase the skills he had. After all, you could know all the skills in the universe but if you didn't know how to use them under the pressure of a fight with the adrenaline going, they were useless.
