Sorry I don’t have money
can I plz have a diamond membership?

plzzzzz. I just want to unlock explorer to become a better chess player.
Yet you only play blitz and bullet.

Honestly, improvement is just down to experience and research. So, I don't think membership is necessary for improvement. There are fantastic FREE resources online, like watching GM streams, youtube or just self analysis after your games.
