I consider kendo strategy a matter of decision making and choice. Nothing is as futile as continuing a strategy that is not working. In kendo these decisions and choices happen in an instant. Changing or adapting to any situation is really all about accepting that something is not working and deciding or choosing to change. In kendo we adapt by having pre planed or practiced scenarios of attacking, similar to being locked out of the house, try the front door, back door, windows and so on until you gain access. Making quick decisions and adapting is something that takes lots of practice and can only be made in the realm of keiko or free practice. We all have choices and decisions in the method and strategy we use.
