So I'm participating in a chess tournament in a few days (FIDE rating) and I'm in a fix as to preparation methods. I'm doing as many puzzles as I can and preparing many openings. I'm also playing few precursor tournaments for practice. But is there any specific approach I need to take? Like I need a 1500 plus rating for my next year's pocket money so is there anything you need to do to get to get an extra edge over the competition?
