And Obi-Wan certainly did not have more power in the Force either.
That's what I meant. Obi was one of the best swordsmen of his time but Dooku totally outmatched him by using Force. I don't even think that Dooku was so much stronger in the Force, than Obi, he was just more talented in utilizing it, while Obi wasn't strong in defending against Force.
What you mean fencing skills?No they were not. Dooku was the Master of Makashi, the ultimate fencing form.
Mastery of forms is mostly irrelevant at that point. They are both Masters and had decades of experience in combat to be able to counter every possible move. Obi learned his weaknesses after fight at Geanosis.
Cin Drallig was master of 6 forms, Academy lightsaber instructor and finest swordsman, yet, Anakin killed him and his apprentice with ease and singlehandedly.
In saber fight between Obi and Dooku deciding factors would be natural abilities and talent.
