It was a typo, don't get so serious. I meant saber combat. When have you ever seen me say "force combat" with the exception of that one time.. And Dooku feared Sidious because Sidious overall was more powerful, not to mention the strategist behind all of the events. Just because he was better than Sidious in saber combat, doesn't mean he's going to have the testicular fortitude to challenge his master who is leagues above him in force abilities.
