Starting with a single neck tie and controlling the other elbow (right hand gripping the lower back of their head, left hand below their bicep, controlling their arm). Drilling them trying to move their right arm inside my left to control my inside elbow. Block that by pressuring my left hand against their belly. If they go outside… grab an underhook, under their right shoulder deep on their upper back. Very important to pressure down on them to avoid them stepping inside my foot and throwing me. Slowly circle back and towards the under-hook side to take them down. Plan B is to step inside their foot, and bump their leg back above the knee to help them fall.
If they aren’t allowing the under-hook; holding the neck tie and their arm, pressure forward. When they pressure back, pull their head down and under my armpit. grab an under-hook with my now free arm, circle back and take-down.
