Strings, or preset series of attacks, can be effective initially. Often, when blocking a string, you don’t know when the string will end, and take action at the wrong time. Some strings are also completely safe on block, which can lead to their abuse. With study, however, these strings become a liability, or a mixup of “will I or won’t I” at best. Opponents who do not realize this and use entire strings every time should be punished to the fullest extent.
