Disclaimer: This is not bragging.. I am simply sharing a story of what happened last night in BJJ class to show the effectiveness of such a move. k.thnx.bye. So last night I am rolling w/ this kid and I throw up this move : http://lockflow.com/article_view.php?id=366 : which I have tapped people out before with. Well the kid decides to resist after I have the move fully applied but because I have my forehead buried on his chest/neck area he cannot forearm me so he just holds his breathe and posts both arms while arching his back. Well I proceed to apply the squeeze and wait this out. I hear the air being squeezed out of him and after 3-5 seconds he taps my face and I promptly release. He then proceeds to go on the offensive and I say "Dude, You tapped!". He says "I did?" then lays down backwards and begins crying loudly for about 7 seconds and then stops crying and asks me "Where am I?", "What happened?" I then tell him that he got knocked out and he doesn't believe it. Then he lays back and begins crying again and comes to again. We told him that he got knocked out and was crying but he has no memory of ever crying and it took him a while to regain his senses. The point of this story is that I never knew this move could do that. I just thought it caused pain to the ribs more than anything. I will definitely be using this at the next comp. BTW. Kid was fine after 15-20 minutes. CLIFFS: Applied said move. Training partner did not tap and got knocked out.. started crying.. and came to. Weird. Move is effective.
