The Head Scissor is an old school move. I have seen it multiple ways and depending on how you do this move can vary on the type of finish (choke, neck crank, face squeeze). It's important that you know the rule set that you're competing under before you try and use this move as some competitions will not allow it. This particular setup comes off of the North/South Kimura position that we have been working on in the previous videos. If you remember I really emphasize the shin over the bicep.
