Get a coach.
A great deal of the 'necessities' in chess you can find on your own. But once you come to the point of not knowing any longer how to use them to progress, it is time to get someone who can look at your specific play and help you discover new ways to use what you know.
I don't know if this is the right spot to ask this so I apologize if I should have made this elsewhere. I'm close to 1600 USCF rated but I need some help to push my game further up, I can't seem to do it on my own anymore. I don't know if I am studying wrong or maybe hit a wall and not working around it as I should but I am getting frustrated. I feel like I have a lot of pieces to the puzzle but I never learned chess in a systematic way so I don't have basic pieces that I should and I think it might be part of my problem but I've exhausted myself trying to patch up the areas and move forward. So I'm reaching out to the chess community here in the hopes of some guidance. Maybe one of you has some time to kill and could help me work on my game, or just add a few thoughts of advise or encouragement from someone who managed to push on and get the puzzle pieces to fit together better. Thanks for reading, hope I don't get trolled for sounding pathetic, just frustrated.
