Hey Doc, this is completely random, but apologies as I don't have a way to reach out more directly :P
I wanted to see if you had come across this Gary Kasparaov Masterclass (very high production online course) about chess. No idea how great of a specific learning experience it would be, but based on what I know about you, the cost might be worth it solely for the entertainment value. Give a watch to the trailer at least. Here's the link: https://www.masterclass.com/classes/garry-kasparov-teaches-chess
