Stuck on 900 ELO
Try working on plan making, and avoid going for one move threats as sometimes it throws away the harmony in your pieces.
Hi I just looked at this post. Maybe I can write more when I have looked at games but I thought I'd write some thoughts here after I asked one of my friends (stronger player than me) about this ~
1. I notice you analyze some but not all games; maybe try to analyze more of them and be intentional about understanding what was going on in them, what mistakes to make and how to avoid them in the future.
2. Playing 15 | 10's may help because then you have time to think things fully through. This, my friend says, made a big difference for him.
3. When I was at about your level I did a lot of puzzles and that helped me a ton. You have a membership so you can do puzzles as much as you want.
