It covers
- difference between being on your side, up on your elbow or up on your hand
- using your hands to block & deflect
- using your feet on the hips and shoulders
- replacing the posts if they knock them off
- what to do if they lift your legs (double under pass, smash pass)
- what to do if they pin or trap your legs (knee through pass etc.)
- lots more
Generally how to maintain open guard and prevent the common passes. Its no-gi and it fits in very well with all your 10th Planet Guards, allowing you to scramble a bit more in between half, butterfly, closed etc.
