so i came upon a new submission (new to me) while rolling , i was on bottom and my rolling partner was in side control on MY right side. i like to do a sort of rubber guard where i grab my left ankle with my right hand. i can usually control my opponent better this way and it makes escaping way easier. so this time he got a bit frustrate in my side rubber guard and decided to get an underhook on my left leg, then everything clicked, i posted my hand on the side of his face, pushed his head through and locked up the triangle, it took about 30-45 seconds for me to adjust it correctly but i finally finished it. that was about 2 weeks ago and i have caught 3 other guys with the move now. my questions: Does anyone else use the side rubber guard? how often do you see the inverted triangle from side control?
