Gyaku-zuki

(reverse punch). This is simply the adaptation of the straight punch used when the attacking fist is on the same side as the rear leg usually in 'zenkutso-dachi'. It is very commonly used as a counter-attack after having parried with the hand or arm on the side of the forward leg.

When beginning this technique, the hips are at forty-five degrees to the line of attack. Twisting the hips so that at the moment of impact they face the opponent or target squarely (or so that the hip on the attacking side is even a little in advance of the other) contributes enormous power to the technique.
