Thumbs up! I watched this video once. And just in the same day, I went up 100 points in 3min chesscom because of applying these concepts. I have subscribed to this channel. The info here is amazing.
Watch some Ben finegold or Anna Cramling they are both d4 players who’s main tool is the queen’s gambit. Ben is funny and has lots of consents and rules that are helpful for beginners and intermediate players. Anna is more bubbly but her play is solid.
