should you buy a fancy membership?

Well, if your not that rich, don't, because a basic membership has many features, you can still play and analyze (once a day) games with it. you can still study chess by videos, a friends,...

and you can still do puzzles with it.

But if your rich, sure! it has a lot of features like the insights, infinite tournaments, no advertisements.

Currently, I have a basic membership and I'm ok with it.
