2 hours ago, Daronil said:ANH's duel was pretty clunky in parts, especially Alec Guiness's little "spin". But I remember talking years ago to a kendo practitioner who had seen many duels between kendo masters, and he was saying that (a few clunky bits aside), the Obi-Wan / Vader duel was the most realistic of all of them. Two masters hardly move at all, apparently. There'll be a few tentative "testing" strikes that are easily parried as each gets the measure of the other, until finally one will hit home quickly in an unanticipated strike that finishes the fight.
I doubt that applies to Jedi and Sith - if the Force allows you to anticipate a second or two into the future, you really need to be outmaneuvred to lose. Also, this doesn’t really mesh with the various lightsaber forms (realistic or not).
