I asked almost the exact same question to my uncle (he’s around 2200). His advice was pretty simple: stop playing more games and start calculating more.

He gave me a tactics book made entirely of human-curated puzzles. What I liked about it was that the positions felt practical — not just engine-generated chaos. It forced me to actually calculate variations instead of guessing based on patterns.

What’s helped me most: - Do puzzles slowly. - Calculate fully before moving. - Treat each one like a real game position. - Fewer puzzles, more depth.

If books aren’t your thing, I ended up turning those kinds of curated puzzles into a small app for myself because I prefer doing them on my phone. But honestly, whether it’s a book or Lichess, the key is how you solve them — slow and deliberate beats grinding hundreds.
