Pull the trapped hand to the waist as you drop into a cat stance.
Theory: The attacker’s reaction is to pull away.
Control the trapped hand with your right hand and vertical snap punch to the jaw.
Front kick to the inside of the attacker’s thigh to open up his/her stance.
Drop down and place your front leg behind the attacker’s lead leg.
Release the trapped hand and grab the back of the attacker’s obi, and vertical elbow strike the groin and pull backwards simultaneously with your lead leg. (Kuchiki-taoshi)
Note: This will take the attacker to the ground.
Note: In the IWKA version your elbow is placed on the knee (RH) and the heel pick is made with your (LH). (Kibisu-gaeshi)
