Improving Your Chess - Resources for Beginners and Beyond...

You should learn most important principles of a chess game. That will give you a solid understanding of a chess game and you will know what to do in every position. Then, you should optimize your calculation so you don't miss tactics in your games. I can help you with all of this. Message me if you are interested.

Use engine analysis and gain more respect as how little tweaking moves can result in sizeable long-term advantage. Becoming a positional player inherently means that you will gain in accuracy - because you understand the game on a different level now.

Still, even at my level, accuracy tends to float between 65-92%.

keep playing and keep improving

You need to think even more carefully.  Really try & guess what move they might play next on their turn. Good luck

If you don't feel confident with your accuracy you must receive help from AI, play against bots of your level and think of the opponent and yourself in between the moves as your own advice from someone who's trying to get good at chess who is listening to professionals

You will have a higher accuracy rate when you use a system or opening that you use all the time. You'll be used to making the moves and having similar positions.
