not many at training today. We did a closed guard attack sequence. If you can get your opponents arm accros his body you set up to attack the arm bar. if he postures up work the same side lapel out and wrap his arm. He will not like this and posture up, then feed the lapel round the front of his neck and hit the sweep to mount and finish. If his steps his leg up to retain his balance. under hook his ankle pull his leg straight lay accross his. leg for the sweep to mount.

As a side note the only real defense is to cross your other arm over to his collar as if you were attempting a choke and free the arm. Easier said then done.
