I recently played an OTB tournament yesterday, it went ok with 2 losses and 2 wins with one of those wins being against a 1476. However, in my losses, I really struggled with positional play. On chess.com, people still blunder at levels like 1700 so you can take advantage of these and win games. However, when your playing OTB chess, your opponent's will almost never make obvious blunders and the game is mostly decided on the positions that you are given. I struggled with this since im not always the best at creating weaknesses within the positions and exploiting them. Are there any channels/books that are recommended for improving positional play?
