bingo. From the view of something like fencing, you are are attempting to get into a position of an explosive lunge. You want to be in range but not let your opponent know you are. In addition to the moving around, there would be small moves in and out. Moving to your 'handed' side also has some advantage. So a right handed fencer would likely favor circling to their right. Both opponents are quickly judging foot position, hand and weapon position, where the eyes are looking etc. Many small fients and repositions are happening quickly.Umbran said:One thing folks seem to have missed - it is easier to not "telegraph" your next attack or movement if you are already moving, rather than stationary.
Elder-Basilisk said:Nor did armies fight that way when it actually came to fighting. Their manuevers were (especially in the ancient world) generally a lot more linear. Yes there were flanking and encircling manuevers, but those were more generally one flank of the an army marching around or smashing through a flank of the opposing army to strike the main force in the rear or in the sides than the kind of mutual circling you suggest.
