1800->2000 rapid

For those in this rating ballpark and above - what's the best advice you have for going from 1800 to 2000 playing rapid on chess.com?

Join chessable and focus on strategy and ending books. Openings can be easily improved analizing your own games and with databases.

In that rating range, games are more often decided by a good strategy and in the endgame and less by cheap tactical trucks. So I agree with #2. You'll need a course/book that is designed for this rating range. Take a look at Artur Yusupov's book series Build up your chess/ boost your chess / Chess evolution. The series covers all the fundamental parts of the game that are needed to improve. And check out IM Andras Toth (chessCoachAndras) on YouTube. He has a list of books he would recommend for I think players around 1800 Fide what's probably somewhere around 1950-2050 Rapid on this site here. Those might help you but you're still gonna have to put in the hours. Good luck!

I highly recommend the WoodPecker Method. Chessable has a great interface for it. The authors did a study and found this, it's crazy! Once you see this, you'll understand why tactics are so vital: Percentage of decisive games decided by tactical mistakes

Currently starting on the School of Chess Excellence Series by Dvoretsky think it is good since you really have to work!
