1. In the top position,
hook one of your opponent's ankles in the crook of your knee, so that you are out to one side of him. You will essentially be sitting on one of his
ankles, with your calf threaded under it. The leg you use to hook his ankle should
be the opposite leg from the one you are attacking--that is, hook your right
leg around his left ankle, or left leg around his right ankle.
2. Reach one arm
underneath your opponent's body and across, and the other over the top and
across, locking around his near arm and head. Your hands should be locked near
the side of your opponent's head and his ankle should remain trapped.
3. Use your locked arms
to suddenly and powerfully suck his head and arm down under his body.
4. As his head goes
under him, sit out onto your side. His head will go all the way underneath
himself, stacking him up on on his shoulder blades. The hooked ankle is now an
anchor helping to hold him in place and prevent him from birding. Squeeze tight
until the referee stops you.
