Check out victor hugo. He has a meeeeeean gi knee bar game. Prolly can YouTube him if you don’t have flo. Brehs lick they chops at black belts nothing feels better than saying “yeah I choked out a blackbelt” when your a lower rank lol. Knee cuts are still legit legit. Just a pain to pull off when someone plays inside de la riva then go into inverting or bolos but that’s a convo for another day lol
