Dooku told Yoda in Episode II that the contest could not be settled be their Knowledge of the force, but by their skill with a light saber. Well.....they tied in that too. Yoda failed to beat Dooku and Sideous. Actually both of the duels were tied, but Yoda still failed. If Yoda could not beat Dooku what made him think that he could beat Sideous? Anyway my point is they both had force lightning and were very skilled with a saber. So my question is was Dooku as powerful as Sideous?
