Whenever I roll with professor and get some extended 1 on 1 time I always try to make it a point to take note of the little things he tells me, as they go a long way.
Just a couple small details from today. When on top in half guard, it is essential to go 2 on 1 and break the grip if the opponent on the bottom has a deep collar grip on your lapel.
When passing open guard, keep the legs forward and low, and keep your posture up tall and back. Don’t try and pass from a wrestling stance.
