Notes

• Start by getting wrist control like I am going for a kimura.  That will keep him from basing out on his arm and preventing the sweep.
• The sweep actually is off to the side at about 45 degrees – not straight back.
• Throw your opposite arm across his face over his opposite shoulder.
• Try to hip bump really high into his chest – and drive your knee into his armpit.

If unsuccessful, try to come down into omoplata (untried as of yet):

Notes

• Keep your head pressed into opponents heart.  Any lower, you can get caught in D’arce Chokes.
• When you are ready release the lockdown, do a leg curl with the leg that is still hooked with his so that you bend his leg towards your butt.  This helps aid the sweep.
