Demian Maia Seminar: Part I...

Here are a few of the quick takehomes from a seminar with Demian Maia. 

i) Tighten armbar from side mount by grabbing arm and trapping with shoulder when in tripod; leaves options for straight armbar.

ii) Push arm across opponent's chest via elbow to weaken muscle strength when opponent is gripping gi and defending armbar attack.

iii) North-south choke from tripod; trap opponent's head between rib cage and arm after securing opponent's arm in armbar attack; then reach under opponent's neck and use own ribcage and bicep to apply choke.

There were also a few things on generally tightening the armbar attack by denying the opponent space and ensuring you apply your weight to his body. 

There will be other things I recall but I am still digesting the wealth of information and processing it!
