This technique is excellent, if you are like me you have felt the frustration that comes with the lock-down. This technique is notorious for stalling and if could be quite uncomfortable as well.
To pull this move off all you have to do is push your opponents down forcing his back to the mat, and then standup on the trapped leg and lean back. This technique literally traps your opponent, trapped as in making his legs into a literal knot that only you can untie.
