Jedi or Sith

Josh ran to Speedy but he disappered. In seconds you saw Josh was getting pounded by nothing. The fight wasn't long. By mere chance Josh reached out and hit Speedy. He grabbed Speedy and threw him out of the arena.

"Speedy out, Josh wins". The proctor said. "You got lucky Josh". Speedy said. "Up next...". The proctor was saying. You heard some kid's name called Phil and yours. You and a fat kid got on the arena. "Ready, fight"! The proctor said. You turned on your lightsaber, Phil did the same. What form should you use on him?
