Learning leg locks can be a super powerful weapon against more skilled opponents. There have been many blue belts that have caught unsuspecting opponents much better then them with ankle locks. I was talking to two World BJJ champions the other day and the subject leg locks came up in the conversation. One World Champion said that he didn't like leg locks very much which was basically an indicator that he didn't really practice or place a high priority towards incorporating them into his training. As a World Champion he is obviously very good and has been successful without with this approach. However, IMO this is an aspect of complacency that could come back one day to cause him problems in a tournament or on the mat. I've been a black belt for a little more than 2 years now and I have the privilege to roll with a third degree black belt world champion (not the one who doesn't like leg locks) on a regular basis. His skills greatly surpass mine though I have been adopting a strategy of using leg locks against him with some success. I've rolled with other black belts of equally high caliber and landed some good leg locks as well. 3X World Champion Denilson Pimenta - Free BJJ Instructional Videos ===>http://bitly.com/1AqHuBU Suffice it to say, "I love leg locks" and use them to win on the mat.

Worthy of note is that BJJ roots came from Judo and that Judo once incorporated leg locks into their art.
