For the competition minded, a tactical analysis of the match areas for Karate, Judo, or Kendo can yield some interesting insights to how to deal with an opponent. The competition area is flat and usually square so there is no terrain to hide in or use for cover, but there is terrain that limits or enhances movement. If you have studied the game of Go then you will be able to appreciate corners, edges, and the center in both defence and offence.
Often in competition, you see two contestants circling each other, or one circling the other. Sometimes when the clock is ticking down, the person that is ahead in points circles to avoid combat and wastes time to win the match. The person that is behind wants to force interaction to try and catch up, but lets his opponent win at his strategy of letting time run out.
By eliminating opportunity for your opponent to circle, you can immediately and effectively limit the opponent’s freedom of movement to half the competition area (if he declines to attack) simply by shifting to cut off the circling (see figure). By shifting, you are using the edges of the competition area to support your flank and limit the opponent’s movement to that side. He is forced to circle the other way, attack or withdraw. Edges can also be effectively used to limit a strong opponent’s to attack on his preferred side (left or right).
A few more shifts and you can maneuver him into a corner. When your opponent is in a corner, he has to divide his attention between you and the match area boundary, which invites a mental Gap (Suki) that can be exploited if you chose to attack.
In a corner, two sides restrict movement. Your opponent has two options; he can either attack, or avoid. Avoidance can take two forms, 1. He can step out of the match area in which case he will get penalized, or 2. he can try to slip out one side. Using maneuver and just offering combat by shifting to block the opponent’s circling means you have degraded the opponent’s freedom of maneuver. Further degrading it into a corner now allows you anticipate a reaction—coming at you, stepping out, or in a moment of indecision your chance to attack. Depending on the opponent and his strength and weaknesses you can choose to attack or counterattack based on your preference.
Using the center, edges and corners of the match area tactically.
Taking the centre of the match area can create a psychological advantage right from the start. It also does not impede you because you are not affected by edges as much as the opponent who is forced toward them. Competition area geometry of the at the tactical level can have great effects on the outcome of the match if you can capitalize on it—but first you must be aware of it. There are other ways to analyze the competition area tactically, I leave it up to you to discover.
One factor that we typically loose sight of in the Dojo in Tactics is the effective use of terrain. Not all combat is likely to occur in an area were there is a clear unobstructed area to maneuver, and terrain can be an advantage or disadvantage, depending on how you utilize or fail to utilize your environment.
Take these ideas outside competition and consider how your environment can create advantages and disadvantages. Edges such as a wall can limit movement but also protect your back in a scenario with several opponents. Many Kata consider confined spaces, such as using a sword in a narrow hallway.
Terrain is a major consideration in modern tactics, why should it be any different in the martial arts? There are literally countless examples of using terrain to advantage during combat. As one example, 17th century swordsman Araki Mataemon used a bamboo grove to his advantage while fighting Yamada Shiryukan who specialized in the Kusari-Gama (a sickle with a chain and weight attached). Yamada could not use the chain and weight effectively with all the bamboo stems and died at the hands of Araki. Mataemon functionally dislocated the Kusari-Gama’s advantage by luring his opponent into the bamboo. He used terrain to his advantage.
The use of terrain in combat includes, barriers limiting the opponent’s movement or protection against the opponent’s techniques. You can use terrain to hide your entire person or just part of your body etc. You may even find some of these ideas in your Kata. Karate Kata show ways of using sand, rocks, farm tools, boat oars and even turtle shells as ways to use the environment and terrain to your advantage, as well as night fighting and fighting on boats.
Application of some of these techniques include fighting along narrow pathways between rice paddies. Iaido has Kata that reflect limitations imposed by the environment, such as narrow hallways, obstacles overhead, and even friendly noncombatants. Even some Engagement Postures (Kamae) in Iaido are related to environmental constraints (e.g. Hasso no Kamae and Waki no Kamae).
Practice in different environments to get used to the variation in terrain. Not all fights will be in areas that are free from obstruction or allow freedom of movement. Think about how your martial art uses these ideas in relation to individual techniques, tactics, and a combination of both.
