Kokyu-nage 4th form attack

Your partner catches you by the lapels with his right hand. With his left he punches at your face. Side-step to your right by moving your hips and head. Deflect his blow by using your left hand, making sure that your arm is straight and that feeling is coming out of your fingers.Now turn into his body with your right arm coming under both of his armpits. Do not try to lift him over but lead his body down to the mat. Your left hand is still in contact with his left arm and now lead him down to the mat.
