Renegade of Funk
Round 1: This is Anakin's Berserk mode, this is the mode he is most powerful using the force. He has dark side powers, and etc... This is the mode he is most force sensitive in and is fueled by the dark side, so he wins this one easily
Round 2: Anakin will try to outmanuever Grievious, and since Anakin is alot faster then Obi Wan, he's going to take this one.
Round 3: I think what your saying is Anakin using the force to duel with his saber, but not any force powers such as Force Push, or Force Jump. I think Anakin can take this, but in a very hard fight. Since Anakin didn't use the force when fighting Dooku alot, and still beat Dooku, taking the note that Dooku can still beat Grievous but with difficulty, Anakin can take this but it will be a difficult match.
