First, I recommend playing games with longer time controls. With confirm move on. Daily games are great for this exercise. Second, ask yourself three questions during each move, and jot them down on a notepad if needed. 1-If your opponent could move right now, where do you think they would go? (CCT) Choose two moves you believe they would make. 2- Choose three moves to counter their actions. Select the one that is both safer and more forcing. (CCT) 3 - Make your choice, then ask yourself: what did I leave hanging? If you write this down in a notebook and follow it for every move, you'll play much better. The key is to keep doing it consistently for each move. Over many games, really, a lot, it will become a habit. Once you reach that point, start shortening your time control until you're playing at the pace you want. After each game, try analyzing it on your own without using an engine, and jot down your thoughts during key moments. This can be really helpful. Then, turn on the engine to review and check your analysis. Hopefully, that will help you play much better, but it will take discipline to make it happen.
