Master Eddie: you are 100% correct. Before Cora, there were no clinching. Now, she introduced them to the lockdown, the electric chair sweep, dog fight, and of course the Rubber Guard. Now more and more, everytime Cora spar, the parents always tell their kids to "Look at Cora"...LOL I even use this to recruit kids for after class sparring session for Cora. I would tell the kids that if they spar with Cora, she will put on moves that they haven't seen before and if they do well against her, they are ready for anyone that's out there...
