Newaza:
what we are covering on the grass and carpet at the moment is the strategy where we have an attacker bigger, heavier and stronger so we can't do the usual mount escape - the answer is to shrimp and put him in the guard
as you know there are 4 variations on the elbow shrimp escape, taking into account if he inserts hooks, as a grappler would, or if he has a lot of weight on his leg, making it heavy - as we are developing these strategies for the street not a mat competition, we take into account what REALLY happens - as you start shrimping his kneecap rubs the concrete and he starts to shift his weight off it - this makes your shrimp escape possible
once we get to the guard, rather than play the usual punch defence to submissions, the attacker stacks, so we do the elevator sweep to regain the mount
keeping in mind we have a proactive aggressive opponent he will try to push you away so you take the armbar
alternatively he takes you in a headlock - so we do the escape that gets us the armbar, or we take the back and go for the sleeper
