Learning kendo is far more nuanced for the people who practice the way of the sword than for people that do not. Suki translated means an “an opening between objects.” In kendo suki is an integral part of training, many exercises are purposed to take advantage of an opening in the defense of an opponent. To create an opening or seeing/sensing an opening is to distract an opponent momentarily, counter strike in the midst of an opponents attack, strike before the opponent is ready to strike or after a strike. It is important to see these exercises as glimpses to what an opening looks like using your mind (third eye). It is only through hard training, internalizing, and sensing suki, only then you can use it to your advantage.
