As mentioned in this SFF question:
Count Dooku had superior fighting skills with the light saber than Obi-Wan, and Obi-Wan knows it and probably knew it before hand as Count Dooku was known to have wide fighting skills.
In that situation, when a Jedi knows his opponent is superior to him, is he allowed/supposed to just flee?? Obviously in the movies it wouldn't make for an appealing scene and its better to show the character die (or almost)... But is there any canon reference where a Jedi has run for his life?
