Greatest St. Louis Chess Club Lecture for Beginners/Intermediate Players?

I've seen a lot of their lectures and haven't always gotten a lot of applicable widsom to my game, but this was a recent amazing lecture that's helped me a lot and may prevent me from quitting chess.  It got me thinking of pawns in ways I hadn't imagined and the examples that GM Elshan Moradiabadi gives are very illuminating.  I immediately played afterwards and looked up games too to analyze pawns the way he talks about in the lecture. 

Could this be the greatest SLCC lecture for beginners/intermediate players?  What are your favorites?

"A very important thing is that pawns' main job is to control weaker squares and protect - create a shield in our position." - GM Moradiabadi

highly, highly recommended
