how to improve chess rating?
find what your opponent is planning and avoid the one move attacks like the b3 a4 shit that people be doing
True answer: Learn basic strategy, theory, and tactics to improve your game. Do puzzles, play games, and learn from videos, books, or any other sources of information. All these things will help you overtime.
#1 Biggest note: Stop making moves thinking that they attack a piece or just because it "looks" good. Verbal conclusions are not the way to go. There's someone on the other side of the board, so think from their perspective of what they're going to do!*
GothamChess taught me that, along with half the website.
