82,3 BJJ

It's a nice spring weather - 16C and sun is shining. Todays schedule is work - Youtube - BJJ class.
I have to start planning some exercises for my shoulder.

I have been watching BJJ competition footage. Looking for open guard control and using hooks. It's blurry, but I'll try to remember today:
1) to prevent my opponents head cross my centerline
2) hook atleast one leg
3) catch his arm to prevent him getting my neck
