Technique was when they turtle into your legs from bottom side control, big backstep to follow them to the back of their turtle, knee in to take back.
Position drills from side control. I did terrible.
In rolling I lost a roll with a blue but managed to narrowly escape getting tapped. Wasn't so lucky with the brown belt.
Tonight I'm going to review some more bottom side control and north/south defense. Such a weak spot right now. Body aches are adding up, and my pile of stinky gis is growing.
