The Real Treasure

Each site has its own plus and minus.
Lichess is the best for playing, but no GM training videos (because they would have to be paid, so free stuff comes with a price after all). But the GM Turtles are doing a very good show almost everyday.
I tried Chess.com, mainly for Chess Mentor which is an excellent tool but there are certain problems there that have been debated ad nauseam. And I can't stand a certain individual which is omnipresent :)
Chess24 have the best videos but you cannot download them. You have to use their interface which can be not practical and annoying. But they have the coolest and hilarious GMs/IMs. You can learn a lot with the Banterblitz and seeing how GMs think, and with the training shows. And you have Anna Rudolf...
ICC has the one and only Uncle Yermo, which is another treasure. I may get back to them only for that. But last time I was member, the interface was not ideal for my Mac.

@kifaru @lovlas
Yes they have Anna Rudolf, but what is better about the videos they have there than the videos you can find on youtube?...even a lot of chess24 videos are on youtube.

You wont find Svidlers Grunfeld DVD on youtube.

Anyone who doesn't think that the C24 video content is the best out there is a crazy person.

I think c24 video content is not the best out there. Guess im a crazy person.

While the quality of discussion and the next level intensity of such rarefied debates are the stuff of those with a desire to indulge in heady amounts of ambrosia... ya'll do know I made this topic primarily to drop Ms. Rudolf some classy style luvs right? If you wish to talk killer names though then Ms. Steil-Antoni has got that one.

I'd give a shout to Guramishvilli but we can't have Giri getting jealous now, he might actually decide to a win a game! xD

Careful now. Idolizing a woman as a Goddess can be a kind of dehumanization.
Girls are complicated.
