2 Part Technique - You can feel the opponent's thumb on the back of your neck to determine which hand he is using. Use his hand to twist him down by controlling the cheek of his hand. If the opponent mistakenly pushes you away, he will expose his arm to being submitted. If the opponent grabs the back of your collar instead, turn inside to over hook for control. All take down needs control. Since your over hook forces weight on the opponent's leg, sweep him to the mat using a trip. He might mistakenly turn away from your mount, which exposes his neck to being submitted.
