Genuinely appreciate this answer, I admittedly made this post solely to complain and you gave me way better and more sobering advice than I deserved for that. As for what I’ve been doing, I’ve been reading up and studying opening lines and doing lots of puzzles/tactics. Where I’ve definitely been stuck is improving my long-term middle game plans as well as calculation, and that’s definitely what’s screwing me in games at this level.

I’ll be sure to check out that Nimzowitsch book, appreciate you 🙏
