@Prodigal:
I am awestruck by some of your claims. That you would suggest that Obi-Wan is on par with Count Dooku is completely baseless and unbelievable. By RotS, Anakin is his superior in swordsmanship.
Logical Question: So how is it that he is able to hold off his superior (Anakin) and someone on par with him (Obi-Wan) simultaneously?
Logical Answer: Because, only when Anakin is unrestrained is he above and beyond Count Dooku, and Obi-Wan is no match for Count Dooku in an all out fight, because he is a lesser duelist and a lesser Force user.
Obi-Wan's sole claim to fame is his defense. I will admit, his defense is likely unrivaled as a swordsman. But this does not mean that he can take anyone. We know for a fact (thanks to Yoda) that Obi-Wan is no match for Palpatine (which logically means he's no match for Yoda, either).
In an all out fight, he could not stand against Mace Windu or Dooku either. The only reason he defeated Anakin was because of his rational thinking, his intimate knowledge of Anakin's lightsaber form, Anakin's tactics, Anakin's strengths and weaknesses, and Anakin's state of mind.
The moment that Count Dooku realized he was being duped, he unleashed his trump card: his Force powers. He disabled Obi-Wan very easily, with the Force. Deny it all you want, but he is no where close to Count Dooku in terms of mastery and refinement of the Force. Considering how Dooku has seven decades of Force training, from the two most powerful Force users (bar Luke), I'd say that Obi-Wan pales in comparison.
I hope you bury this issue completely. Your assertions are seriously without any base to them. In an all out fight without Anakin to assist him, Obi-Wan would die against Count Dooku, without too much difficulty.
@Traya:
Honestly, I think the issue is with Lucas' mishapen and odd intentions. I honestly see Dooku as being superior to the duo, when he's using the force offensively. I accept that Anakin defeated Dooku in lightsabre combat, but honestly; what was to stop Dooku just reversing the targets and wasting Anakin with the force and kicking Kenobi backwards? In that case, Dooku would have effectively owned them both.Circumstance effectively gave Anakin a natural advantage and combined with Anakin's raw power and skill gave Dooku something that he couldn't handle.
I can only assume that Dooku chose to put Obi-Wan out of the fight because he wanted to beat him in the traditional sense - in a lightsaber duel. That, or maybe Anakin wouldn't have succumbed as easily to such an attack - given that Anakin's raw command and strength in the Force far exceeds Dooku's (as well as Yoda's and Sidious's as well) own.
However, I don't believe that Anakin would have won (or would have won as quickly) had Dooku not attacked Obi-Wan. As Palpatine has said before, Obi-Wan is Anakin's "restraint". Killing, attacking, or otherwise harming Obi-Wan is a way to really piss Anakin off.
And, when that happened, Anakin manhandled Count Dooku pretty easily, in their saber contest.
