GJ chess
No.
Why
The whole thing has always seemed a little bit false to me, for example his dirty chess tricks videos. Now I'm not saying that they don't work, they do, however in nearly every video he shows them in he claims they're from one of his games. I just find it hard to believe that all of these lines are lines he's personally played. Seems like a shortcut way of looking at chess that doesn't allow for real improvement in the long run. I could be wrong about the GJ chess channel though, not sure what others think of it but no one else has recommended it so far.
I've watched a number of John Bartholomew's videos and I like his style of presentation. He's one of the few YouTube channels to do over-the-board presentations and I have been experimenting with this style myself. Anyone else like this format?
