Aikido v Oh Do Kwan Karate 2 - Yin/Yang

The second time Richard Killblane and Joshua Copson of Blue Dragon Dojang sparred, they were more comfortable with each other. Copson was so good that Killblane could not get any throws, so both tried to control the fight through control of distance. When one advanced the other retreated, when one retreated, the other advanced.
