right left-side inside chain turn into closed

A pattern that Bob Bowlby and Joan Peeples taught me.
Start in an open left handhold.
On 1, prep on line with the follower’s shoulder.
On 2, left prep on line with the follower’s face.
Step 3&4 is over and behind the followers head such that the follower’s hand gets released on step 4 so your right hand can slide down the follower’s head.
On step 4 step back into the slot.
End in a closed position.
