I'm having difficulty with a particular training partner that LOVES this guard pass- essentially securing pistol grips with both hands on the inside of both knees, pulling back then pushing forward as hard as possible to pass. He has about 30 pounds on me and I find it difficult to neutralize his power behind the pass. Often times I try to loop my shin and foot over one arm and from there attempt to go to spider guard- it works sometimes but I still get passed because of his grips. Should I try to just peel his grips first and not let him have them? Are there any effective offensive counters to this pass? What are the weaknesses of this pass that I can exploit to my benefit? Thanks.
