Well first off rating yourself isn’t working for you. If it was you’d be improving. In general you have to pay attention to details and note cause and effect patterns across games. Try watching recorded games as a pre play warmup and slow it down to catch everything. If you want specifics from snother person then get another person to play with you and watch what you do. If i had to guess, your doing things that you think aren’t a big deal that actually are. I’m only 1300 bit DM me if you liked to play sometime.
