Improving My Passing Game

Alex was trying to help me improve my passing game. I showed/reviewed the following two passes:

1. Margarida Pass - Like the knee slide pass, but grab their lapel and tuck your elbow in and down. You use their gi instead of an underhook.
2. Smash Pass - Put your head on the passing side. Hip down smashing their leg. Underhook if possible. One of the key components is to control their arm on the passing side, try to pull it off the ground. This is Alex's favorite because once you're smash passing, it's hard to stop. Can't seem to find a video though.
