Simple and objective content, but I found it short

Playing guard with big guys

Good instructional with some good tips and techniques against a larger opponent. Clear instruction and demos.

Brush up on fundamentals

This is a nice way of revisiting some of the classic and fundamental techniques but from a strategic standpoint. There is a good amount of material about stopping the guard pass and maintaining control. There are some more complex guards towards the end of the video as well.
