Trinity. A master of keylocks is what I meant. Can you remember last time you were caught in a keylock or even applied one? If you answered "recently," your either a very sad jiu jitsu fighter or you love to punish whitebelts as much as I do. Just a few weeks ago I pulled off a one-handed keylock on a whitebelt that was half my size and half my weight - It was awesome!
Anyway, the first time I saw this keylock variation was in an old competition video on the internets, but it was a long time ago and I forgot about it. Then a few weeks ago I found this, and I was like "Ohh snap! That's nasty." This submission is very tricky and also very tight. If you suck in the elbow and pop your leg over the body correctly, you will definitely have that whitebelt running home to mommy. Check out another great vid from LockDown MMA - the keylock variation from side control.
