Youtube has EVERYTHING. There are probably videos of people playing chess with dogs.
Youtube channels to learn chess

I am currently following Blakey's new site. I have big hopes for that one. I will also really recommend Hanging Pawns. Specially his Middlegame videoes. The highligts there will be his easy to understand approach about pawnpushes.

Hanging pawns and dereqe Kelly are best and well organized YouTube channel for all sorts of players especially if you want to learn openings.

What are the best youtube channels to learn Chess for Average players?(1500-2000).

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 would not recommend it outright as gj_chess mainly focuses on the opening, but it is interesting. St Louis chess club is great for learning and agadmator is good for learning the classics.

Best YouTube channels are
dereque Kelly chess
Hanging pawns
Agadmator's chess
you don't have to follow all channel that would be waste of time
, select 2 or 3 channels and follow them
.
If you want to win fast follow chess talk only

A friend of mine (Fide Master) and I run a Youtube channel. Not that big yet, but with 230 videos we are growing day-by-day. Check us out here and let us know what you want to see!

This is a good channel too!
I recently discovered the Youtube channel of Hungarian/Australian IM Andras Toth (Chesscoach Andras). I was pleasantly suprised by how much instructive content he has posted. And I really like his hybrid Australian/Hungarian accent, sort of like Susan Polgar meets Crocodile Dundee!
