When you press his hip down to pin it, can’t he grab the back of your head / break your posture if your positioning is not perfect? I see it as arms against hip and even the pulling power of the legs (an unfair fight that works mostly with speed element of surprise / less skilled opponents) . I would like to use only the safety most effective and most efficient way(s) to break guard. Because of my own experience, Gordon Ryan’s instruction, John Danaher’s instruction, and others, I tend to think this is not the best way to break guard and has more risk of submission to it than standing to break guard from inside control within the the arms (double bicep tie / hands in the armpits neutral grip). I know it (the knee wedge) works sometimes, but I believe standing uses gravity better, and keeps better separation from the hip to avoid triangles and armbars. I’d like to hear your thoughts on this. Best of luck. I just want to stick with only the best techniques, and particularly those that when used gain sufficient distance from the threat of submission holds. Thanks for sharing. It’s good you are open to correction and improvement. I’m glad you can see this as concern about the way of doing things rather than take it as personal, which I believe you are intelligent enough to discern the difference.
