GM Daniel Naroditsky's channel[1] is the best instructional I have seen. His speedrun series is very good. He takes the time to stop and explain his thought process while playing the game. And then after few games he does a deeper analysis and answer any questions. The moment that sold me was when he showed how they use chess engine to do preparations at their rating level.
On a side note, I have been working on a bughouse[2] chess web app in my spare time[3]. It's not ready for HN traffic yet though. Bughouse is not getting a Queen's Gambit anytime soon. But I would love to see more steam behind online bughouse as well. It is my favorite variation. The need for team work and communication makes it very lively.
I watch Hikaru pretty regularly, he's an entertaining streamer, but I'm not sure about the value of watching his video for chess knowledge. He plays these really baffling chess variants (like all pawns + queen vs IM opponent) in hyperbullet (30 secs) or bullet (1 min) like in one of his streams he went on for minutes about how he hates 3+1 because it's "too serious". As someone who exclusively plays 15+10 or 30+20, his streams really just feel like watching a video game stream to me, since it's impossible to understand "the chess" at that speed for a mere mortal like me.
For chess, I prefer watching e.g. agadmator's YT channel. I stop, think, roll back pretty frequently. I can rarely solve his puzzles ("feel free to stop the video..." parts) but without stopping and thinking for a min, I can't even understand the position lol.
