I read this translation article from Andreas Quast. It was written by senior Uechi-ryū practitioner Tōbaru Keichō. It gives a quite good overview about the topic of enbusen. http://ryukyu-bugei.com/?p=7408
The topic is Enbusen but I zeroed in on these lines: As the basic forms of enbusen, there is the ‘I-shaped enbusen‘ (ijikei) which assumes the enemy in the front and back, the ‘horizontal enbusen‘ (yokoichijikei) which assumes the enemy on the left and right, the ‘cross-shaped enbusen‘ (jūjikei) which assumes the enemy from four directions, the ‘all directions enbusen‘ (shihōhappō) which assumes the enemy in all directions, and the ‘enbusen in which the directions and footwork radiates to all directions’ (happō hōshakei). Additionally, depending on the type of kata, various other enbusen exist, such as the ‘T-shaped’ (teijikei), the ‘reversed-T-shaped’, and the ‘tree-kanji-shape’ (kijikei) enbusen.
Multiple directions. Surely one enemy & movement to acheive angles to either setup to gain dominance or bridging to support a technique or escape.
Interesting article never the less.
