Argh this was a really great video. I typed up a really long response in a text editor, which crashed near the end while I was watching the video, so I lost everything
Anyways, I appreciated that you provided an overview of the Ruy Lopez lines and some opening explanation, since what little Ruy lopez theory I knew at the time has left my head.
Also I like your discussion of the small inaccuracies I make that allow my opponent to get a better position. You're definitely right that 6.c3 would've been much better than 6.h3 and that Bg5 was not a great move. I think I should've tried either 6.c3 or 6.Be3.
I'm glad i found accurate moves once I had a tough position! But, I completely missed Nd3. The knight would've been great on d3. Thanks for the idea!
The discussion of the ideas surrounding my decision to trade on e5 and play c4 was great (even thought my decision to trade on e5 in the game was far from great

)
I had forgotten how complicated that endgame was. I'm pretty happy with my play overall (considering my opponent was a grandmaster).
Thanks for the analysis it was very in-depth and instructive!
