Ai-uchi

In free-sparring, ai-uchi commonly occurs when two opponents strike each other at the same time so that their points cancel each other. It also means being willing to give up a point so you may earn more points, such as taking a one-point kick to the abdomen while delivering two-point kick to the opponent's head.

Mutual strikes also occur when two attacks collide, such as when two punches meet head-on. If both punches were delivered correctly, their collision force will not be at its maximum since the power of both punches being focused at the targets, not at the point where the fists collide. If one punch has more speed and power than the other, the fist may not be harmed, while the other fist may be injured.

When free-sparring, you should be aware of ai-uchi and use it to your advantage.
