Here's a question from a newbie white belt. Last weekend I was rolling with a guy much bigger than me. He's got about 2 years experience in BJJ (off and on) and probably outweighed me by about 40lbs. He was basically having his way with me since my grappling/submission defense is pretty poor being so new to the sport. Anywho, I ended up on my back and slapped on a tight triangle (arm in). I thought I was in pretty good shape, although I have yet to be shown the proper technique of utilizing the triangle. More than anything, I was just trying survive on bottom. He struggled for a bit and then started crankin on my ankle. I tapped pretty quickly since I wasn't expected it nor did I have any previous knowledge to defend against it. What is the proper way to defend something like this? I do realize that if I had been applying the triangle effectively it probably would not have happened. Thoughts?
