I think everyone hits a few plateaus now and then. My first was 1300. Then 1600. Then breaking past 2000 took a while. Now reaching 2200 feels like a challenge.
But, like every plateau, there's usually a reason that you're stuck—something in your game that's lacking, or needs correcting.
Do you review every game you play, to find your mistakes? If not, do it. You can use Stockfish here on chess.com to help you review.
Are there any openings you feel uncomfortable facing? If so, don't hide from them—study them and work on them until they don't scare you anymore.
Do you run into moves where you don't know what to do, and are searching for a plan? Sometimes this could mean you're missing tactics—but a lot of the time it means you lack positional knowledge. Have you read any positional books, like Nimzo's "My System", or Silman's "Reassess your Chess"? I recommend doing so, if you haven't.
Aside from that, it might be time to start honing an opening repertoire, if you haven't already. Practicing important endgame positions certainly can't hurt, either.
Keep at it! You'll break the wall if you keep pushing forward. One step at a time. Best of luck!
Sup fellow Chess homies. Been playing Chess since high school and steadily progressed till I hit this crappy 1700's invisible wall. My Chess.com ratings here is almost in sinc with my USCF (1780). Except my game here seems to fluctuate a little more in the high 1600 - mid 1700s range. Been in this limbo a long time now.
Anyone here had this experience? Your method of conquering "the wall"?
