So this whole week, we been drilling the hip bump to fail kimura to fail guillotine to 100%. I think Cora is getting the hang of it as she is able to toss me around like a rag doll, mine you, I'm 160 lbs. Anyways, today at the gym, her coach was teaching them 3/4 Nelson to counter a takedown. I watch them carefully and it look like the 100%. He went on to say that its a neck crank and might not be legal in tournaments, but its great to defend a takedown. So is the 100% a neck crank? Is it legal for kids to use it? Need to know so I can tell her not to use it tomorrow. Thank you...Bruce
