Yes. Premium members should have lots of fun on chess.com although if you're not one, you still have lots of fun because chess.com is such a great website.

Personally I think the videos alone would be worth the diamond membership cost alone.

You should become a premium member because they get access to really cool stuff like different chess sets. You can get access to everything if you're a diamond member. You can get better quicker and faster then when you're a regular member. It rocks!
